RANDOMVARIABLE

Random variable

In probability and statistics, a random variable or stochastic variable is a variable whose value is subject to variations due to chance . As opposed to other mathematical variables, a random variable conceptually does not have a single, fixed value ; rather, it can take on a set of possible different values, each with an associated probability.
