Key Concepts

Random Variable

A random variable is a function that assigns a numerical value to each outcome of a random process. It quantifies uncertainty by mapping outcomes to numbers, allowing the use of mathematical tools to study randomness.

Discrete Random Variable

A discrete random variable is one that takes on a countable set of values. When counting occurrences or items, such as the number of children in a family, the variable is discrete because it can only take on whole number values.
