WebDefinition. A probability mass function (pmf) is a function over the sample space of a discrete random variable X X which gives the probability that X X is equal to a certain value. Let X X be a discrete random variable on a sample space S S. Then the probability mass function f (x) f ( x) is defined as. f (x) = P[X = x]. f ( x) = P [ X = x].
