# Discrete Random Variable

Variables are defined as characteristics that changes or vary over time and/or for different individuals under consideration. Variables are of different types.

A variable $x$ is a random variable if the value that it assumes, corresponding to the outcome of an experiment, is a chance or random event. Random variables are classified as either discrete or continuous, according to the value that $x$ can assume. In this section we will be discussing more about Discrete Random variables.
