👉 In mathematics and computer science, a random variable is an abstract mathematical concept that represents a numerical value determined by chance. Random variables are used to model real-world phenomena where outcomes are uncertain or unpredictable. They are fundamental in fields such as statistics, probability theory, machine learning, game theory, and quantum mechanics. Random variables can take on any possible value within a specified range. In other words, they represent an outcome of some experiment or process that cannot be predicted with certainty. The values of random variables
