What is stochastic variables?

Stochastic variables, also known as random variables, are quantities whose values are determined by the outcomes of a random phenomenon. They can take on different values based on the inherent uncertainty of the process being observed, and are typically classified as discrete or continuous. Discrete stochastic variables have a finite or countably infinite number of possible values, while continuous variables can take any value within a specified range. These variables are fundamental in probability theory and statistics, as they enable the modeling of randomness and uncertainty in various applications.
