# Normal Distribution With Examples

In the previous two articles of this unit we learned Binomial distribution and Poisson Distribution, in this article we will learn Normal distribution.
Normal Distribution

# Poisson Distribution With Examples

Now we will learn Poisson distribution. In the previous article we learn Binomial distribution. So let’s start.
Poisson Distribution
Definition
Let X be a discrete

# Binomial Distribution With Examples

Binomial Distribution
Before starting our discussion on Binomial Distribution we have to understand what Bernoulli Trials is.
Bernoulli Trials
Trials are called Bernoulli trials if

# All About Moment Generating Function With Examples

Moment generating function
In this article we will first learn what a moment generating function (mgf) is and then we will learn how to use

# What is Covariance?

Covariance Definition
Covariance is a measure of association between two random variables. Let X and Y be two random variables. Then the covariance is defined

# Variance Formula of Random Variable With Example

Variance
One of the important measures of variability of a random variable is variance. Let X is a random variable with probability distribution f(x) and
