How are random variables generally identified (i.e., what notation is used to identify a random variable)?

A random variable is usually denoted by capital letters X, Y, Z.
Explanation:
Capital letters such as $X,{X}_{1},$ Y are used to denote random variables, while lower case letters #$x,{x}_{1}$, y, are used to denote their corresponding values.
