Discrete Probability Distribution
The variable [latex]X[/latex] is classified as a discrete random variable if it takes a fixed set of possible numerical values and it is not possible to get any value in between.
discrete probability distribution
The probability distribution of a discrete random variable describes all possible values of the random variable, as well as the probability associated with each value.
A discrete probability distribution is often presented in a table or graph.
Discrete probability distributions can be represented as a bar graph as well. The bar graph should include all of the possible outcomes of the discrete variable and the probability associated with each outcome.
