following: Before Going on to the examples let’s understand some properties of PMF as well. The probability mass function p(x) is positive for at most a countable number of values of x. That is; if X must assume one of the values x1,x2, . . . , then 1. p(xi) ≥ 0, i = 1, 2, . . . 2. p(x) = 0 for all
