Xiaojie Liu / Investopedia How a Random Variable Works Random variables are used in probability and statistics to quantify outcomes of a random occurrence, and they can therefore take on many values.

A probability distribution, usually displayed graphically, shows the relative likelihood of all possible outcomes occurring within a specific time period.

Explain why probability is important to statistics and data science. See the relationship between conditional and independent events in a statistical experiment. Calculate the expectation and variance ...

Random Variables and Probability Distributions Random Variable: It is a real-valued function that assigns a numerical value to each possible outcome of a random experiment.

Random Variable: A measurable function that maps outcomes in a probability space to real numbers, thereby enabling quantitative analysis of random events.
