A random variable is a numerical representation of the result of an experiment in statistics. Any qualities, quantity, or number that can be gauged or tallied qualifies as a variable.
What is the definition of a random variable?
A random variable is a variable with an unknown value or a function that gives values to each of the results of an experiment. There are two types of random variables: discrete (having specified values) and continuous (any value in a continuous range).
What are some examples of random variables?
Every event in an experiment has a probability, which ranges from 0 to 1, and the total probability of the experiment is 1. The number of outcomes from rolling a die, the number of outcomes from pulling a jack of spades from a deck of cards, and other examples are examples of discrete random variables.
