## 2. Random Variable: Definition, Types, How Its Used, and Example

A random variable can be either discrete or continuous. Discrete Random Variables. Discrete random variables take on a countable number of distinct values.

A random variable is a variable whose value is unknown, or a function that assigns values to each of an experiment's outcomes.

## 3. Chapter 4: Discrete Random Variables

A random variable is called discrete if its possible values form a finite or countable set. A random variable is called continuous if its possible values ...

It is often the case that a number is naturally associated to the outcome of a random experiment: the number of boys in a three-child family, the number of defective light bulbs in a case of 100 bulbs, the length of time until the next customer arrives at the drive-through window at a bank. Such a number varies from trial to trial of the corresponding experiment, and does so in a way that cannot be predicted with certainty; hence, it is called a random variable. In this chapter and the next we study such variables.
