If X is a discrete random variable taking values in the non-negative integers {0,1, ...}, then the probability generating function of X is defined as where p is the probability mass function of X. Note that the subscripted notations GX and pX are often used to emphasize that these pertain to a particular random variable X, and to its distribution.
