Discrete Random Variables
Definition
Discrete random variables refer to variables that can only take on specific values within a certain range or set. These values usually have gaps or intervals between them and cannot be measured with complete precision.
Analogy
Think of a vending machine that only dispenses whole numbers of candies. The number of candies you get can only be specific values like 1, 2, 3, and so on. You can't get fractions or decimals like 1.5 or 2.75.
