A variable that can take on a countable number of possible values, often representing counts or categories.

Expected Value

The long-run average or mean value of random variables, indicating the anticipated outcome of an experiment if it were repeated many times.

Discrete Random Variable

A variable that assumes a finite number of unique values, typically signifying the results of a stochastic process.

Continuous Random Variable

A type of random variable that can take an infinite number of possible values within a given range, often associated with measurements.
