A discrete random variable is a type of random variable that can only take on a countable number of distinct values.

The Distribution Function (also called the cumulative distribution function or cdf) of random a random variable, X, is defined by Probability distributions (or pdf's) for the Random Variable Examples.

A discrete random variable is a type of random variable that can take on a countable set of distinct values. Common examples include the number of children in a family, the outcome of rolling a die, ...

Probability Density Function Calculating probabilities for continuous random variables requires a different approach from the methods used with discrete variables. If all the outcomes of a continuous ...
