How to discrete probability distribution

WebA discrete probability distribution is one where the random variable can only assume a finite, or countably infinite, number of values. For example, in a binomial distribution, the random variable X can only assume the value 0 or 1. Statistics and Machine Learning Toolbox™ offers several ways to work with discrete probability distributions ... WebDefinition 5.1.1. If discrete random variables X and Y are defined on the same sample space S, then their joint probability mass function (joint pmf) is given by. p(x, y) = P(X = x and Y = y), where (x, y) is a pair of possible values for the pair of random variables (X, Y), and p(x, y) satisfies the following conditions: 0 ≤ p(x, y) ≤ 1.
