Assume Bernoulli trials — that is, (1) there are two possible outcomes, (2) the trials are independent, and (3) p, the probability of success, remains the same from trial to trial. Let X denote the number of trials until the r t h success. Then, the probability mass function of X is: for x = r, r + 1, r + 2, ….
