The document summarizes the binomial and Poisson probability distributions. The binomial distribution describes the number of successes in a fixed number of independent yes/no trials, where the probability of success is constant across trials. The Poisson distribution approximates the binomial when the number of trials is large and the probability of success is small. Examples are provided to demonstrate calculating probabilities using the binomial probability formula, binomial tables, and the Poisson probability formula with Poisson tables.

The Monte Carlo method can be used to computationally estimate values like pi by simulating the throwing of darts at a circular target.

Uniform Distributionmathscontent

A random variable X has a continuous uniform distribution if its probability density function f(x) is constant over the interval (α, β). The uniform distribution has a probability density function f(x) = k for α < x < β, where k is a constant, and is equal to 0 otherwise. All values from α to β are equally likely to occur, meaning the probability of X falling in any sub-interval of (α, β) is equal regardless of the interval's position within the range.

Binomial distributionnumanmunir01

A random variable is a variable whose values are determined by the outcome of a random experiment and can be used to model probabilities. Examples of random variables include the sum of dice rolls or number of heads from coin tosses. A probability distribution assigns probabilities to each possible value of a random variable. It must satisfy the properties that probabilities are greater than or equal to 0 and sum to 1. Common probability distributions include the binomial and normal distributions.

Poission distributionmohammad nouman

This document provides information about the Poisson distribution. It begins with background on the mathematician Simeon Denis Poisson who developed the distribution in 1837. The Poisson distribution models the number of random events occurring in a fixed interval of time or space. The key properties are that the probability of an event is constant and events are independent. Several examples of real-world applications are given such as disease occurrences, mutations, and telephone calls. The document then provides the Poisson probability mass function equation and explains how to calculate probabilities for specific values. It also discusses Poisson processes and fitting observed data to a Poisson distribution. Finally, it compares the Poisson distribution to the binomial distribution and outlines their key differences.

Discrete Probability Distributionsmandalina landy

This document discusses several discrete probability distributions: 1. Binomial distribution - For experiments with a fixed number of trials, two possible outcomes, and constant probability of success. The probability of x successes is given by the binomial formula. 2. Geometric distribution - For experiments repeated until the first success. The probability of the first success on the xth trial is p(1-p)^(x-1). 3. Poisson distribution - For counting the number of rare, independent events occurring in an interval. The probability of x events is (e^-μ μ^x)/x!, where μ is the mean number of events.

The Binomial, Poisson, and Normal DistributionsSCE.Surat

The document summarizes key concepts relating to three probability distributions: 1) The normal distribution describes variables that arise from the addition of small random effects and approximates the binomial distribution for large numbers of trials. It is used to model natural phenomena influenced by many independent factors. 2) The binomial distribution describes discrete random variables resulting from Bernoulli trials with a fixed probability of success. It gives the probability of a given number of successes in fixed number of trials. 3) The Poisson distribution approximates the binomial when the probability of success is very small but the number of trials is large. It is used to model rare random events occurring independently over an interval of time or space.

Methods of point estimationSuruchi Somwanshi

This document provides an overview of point estimation methods, including maximum likelihood estimation and the method of moments. It begins with an introduction to statistical inference and the theory of estimation. Point estimation is defined as using sample data to calculate a single value as the best estimate of an unknown population parameter. Maximum likelihood estimation maximizes the likelihood function to find the parameter values that make the observed sample data most probable. The method of moments equates sample moments to theoretical moments to derive parameter estimates. Examples are provided to illustrate how to apply each method to obtain point estimators.

Regressionumar sheikh

Regression is a statistical tool used to predict unknown values of a dependent variable from known values of one or more independent variables. It estimates the average change in the dependent variable given a change in the independent variable(s). There are two regression lines - one with Y as the dependent variable (Y on X) and one with X as the dependent variable (X on Y). The regression equation expresses these lines algebraically. The constants a and b are estimated using the method of least squares, which finds the line that minimizes the vertical differences between actual and estimated Y values. Multiple regression uses more than one independent variable to increase prediction accuracy.

Vector spaces Jitin Pillai

This document discusses vector spaces and subspaces. It begins by defining a vector space as a set V with two operations, vector addition and scalar multiplication, that satisfy certain properties. Examples of vector spaces include R2 and the space of real polynomials of degree n or less. It then defines a subspace as a subset of a vector space that is itself a vector space under the inherited operations. For a subset to be a subspace, it must be closed under vector addition and scalar multiplication, and contain the zero vector. Examples given include lines and planes through the origin in R3. The span of a set S of vectors is defined as the set of all linear combinations of the vectors in S, and it

Continuous Random VariablesDataminingTools Inc

1. Continuous random variables are defined over intervals rather than discrete points. The probability that a continuous random variable takes on a value in an interval from a to b is given by an integral of the probability density function f(x) over that interval. 2. The probability density function f(x) defines the probabilities of intervals of the continuous random variable rather than individual points. It has the properties that it is always nonnegative and its integral over all x is 1. 3. The cumulative distribution function F(x) gives the probability that the random variable takes on a value less than or equal to x. It is defined as the integral of the probability density function from negative infinity to x.

Theory of probability and probability distributionpolscjp

Probability refers to the likelihood of an event occurring. It can be expressed as a fraction between 0 and 1, with the total number of possible outcomes as the denominator and number of favorable outcomes as the numerator. A random variable is a value that can vary in an experiment but whose outcome is uncertain before the experiment. Probability distributions specify the probabilities of random variables taking on particular values. There are discrete and continuous probability distributions. Important discrete distributions include binomial and Poisson, while the normal distribution is the most important continuous distribution.

1) Continuous random variables have cumulative distribution functions (CDFs) that are continuous functions of the variable. They can have probability density functions (pdfs) that define their distributions. 2) Exponential distributions describe systems with memoryless properties where the probability of failure does not depend on past events. They commonly model time between events like packet arrivals. 3) Uniform distributions have constant pdfs across their range, resulting in a linear CDF ramp function. They are commonly used in random number generation.

Stabilization Of Operating Point | Electrical EngineeringTransweb Global Inc

This document discusses the stabilization of operating point in BJTs. It defines the load line and operating point, and explains that the operating point depends on factors like current gain, temperature, and supply voltage variations. An increase in current gain or temperature will shift the operating point towards saturation. It also describes different bias circuit types - fixed bias, collector base bias, fixed bias with emitter resistance, and voltage divider bias - and provides their basic equations.

What is the Philosophy of Statistics? (and how I was drawn to it)jemille6

What is the Philosophy of Statistics? (and how I was drawn to it) Deborah G Mayo At Dept of Philosophy, Virginia Tech April 30, 2025 ABSTRACT: I give an introductory discussion of two key philosophical controversies in statistics in relation to today’s "replication crisis" in science: the role of probability, and the nature of evidence, in error-prone inference. I begin with a simple principle: We don’t have evidence for a claim C if little, if anything, has been done that would have found C false (or specifically flawed), even if it is. Along the way, I’ll sprinkle in some autobiographical reflections.

Overview Well-Being and Creative CareersUniversity of Amsterdam

Slides to support presentations and the publication of my book Well-Being and Creative Careers: What Makes You Happy Can Also Make You Sick, out in September 2025 with Intellect Books in the UK and worldwide, distributed in the US by The University of Chicago Press. In this book and presentation, I investigate the systemic issues that make creative work both exhilarating and unsustainable. Drawing on extensive research and in-depth interviews with media professionals, the hidden downsides of doing what you love get documented, analyzing how workplace structures, high workloads, and perceived injustices contribute to mental and physical distress. All of this is not just about what’s broken; it’s about what can be done. The talk concludes with providing a roadmap for rethinking the culture of creative industries and offers strategies for balancing passion with sustainability. With this book and presentation I hope to challenge us to imagine a healthier future for the labor of love that a creative career is.

The role of wall art in interior designingmeghaark2110

Wall art and wall patterns are not merely decorative elements, but powerful tools in shaping the identity, mood, and functionality of interior spaces. They serve as visual expressions of personality, culture, and creativity, transforming blank and lifeless walls into vibrant storytelling surfaces. Wall art, whether abstract, realistic, or symbolic, adds emotional depth and aesthetic richness to a room, while wall patterns contribute to structure, rhythm, and continuity in design. Together, they enhance the visual experience, making spaces feel more complete, welcoming, and engaging. In modern interior design, the thoughtful integration of wall art and patterns plays a crucial role in creating environments that are not only beautiful but also meaningful and memorable. As lifestyles evolve, so too does the art of wall decor—encouraging innovation, sustainability, and personalized expression within our living and working spaces.

The History of Kashmir Karkota Dynasty NEP.pptxArya Mahila P. G. College, Banaras Hindu University, Varanasi, India.

This slide is an exercise for the inquisitive students preparing for the competitive examinations of the undergraduate and postgraduate students. An attempt is being made to present the slide keeping in mind the New Education Policy (NEP). An attempt has been made to give the references of the facts at the end of the slide. If new facts are discovered in the near future, this slide will be revised. This presentation is related to the brief History of Kashmir (Part-I) with special reference to Karkota Dynasty. In the seventh century a person named Durlabhvardhan founded the Karkot dynasty in Kashmir. He was a functionary of Baladitya, the last king of the Gonanda dynasty. This dynasty ruled Kashmir before the Karkot dynasty. He was a powerful king. Huansang tells us that in his time Taxila, Singhpur, Ursha, Punch and Rajputana were parts of the Kashmir state.

1. Density FunctionDensity Function

2. Density FunctionDensity Function  Density Function, for discrete variable is similar to distribution function  It can be considered as a “smoothed” distribution function  Let us suppose ‘X’ to be a continuous random variable. And x be the value that variable X takes. In such case f(x) is used to describe density function

3. x0 ba Probability Density Function shows that the probability of the random variable lies in a particular range. f(x)

4. Probability DistributionProbability Distribution Function (for discreteFunction (for discrete variable) Vs Probabilityvariable) Vs Probability density function (fordensity function (for continuous variable)continuous variable) Binimial probability Dis tribution func tio n with s uc c e s s pro b 0.5 and total # trial 50 0 0.02 0.04 0.06 0.08 0.1 0.12 1 4 7 10 13 16 19 22 25 28 31 34 37 40 43 46 49 Probability Dins ity Func tion Example (Normal Dis tribution with me an 25 and SD 3.2) 0 0.02 0.04 0.06 0.08 0.1 0.12 0 5 10 15 20 25 30 35 40 45 50

5. Density Function: ExampleDensity Function: Example  Suppose your client confirms an appointment between noon and 2pm.  Here, the time of arrival is absolutely random. Let, X = the random variable for arrival time (X=1.5 means he visit your office at 1:30pm) And, x be the possible value, random variable X can take.

6. ExampleExample 0 2 0.5 x f(x) Then, density function f(x) will be

7. Probability Density FunctionProbability Density Function ExampleExample 0 2 0.5 x f(x) 0.5 1 The probability that your client visits your office between 12:30 and 1:00 is given by the shaded area.

8. Probability Density FunctionProbability Density Function ExampleExample 0 2 0.5 x f(x) Note that area between 0 and 2 should be equal to 1 since the probability that your clients arrives between noon and 2pm is 1 (assuming that he will keep his promise that he will visit between noon and 2pm)
