www.math.utah.edu1 Discrete Probability Distributions A discrete probability distribution lists each possible value that a random variable can take, along with its probability. It has the following properties: The probability of each value of the discrete random variable is between 0 and 1, so 0 P(x) 1. The sum of all the probabilities is 1, so P P(x) = 1. Examples
