WebApr 10, 2014 · If X is the number of successful trials, then assuming independence of trials X has a Binomial ( n, p) distribution where n is the number of trials. Then the probability of at least two successes is P [ X ≥ 2] = 1 − P [ X = 0] − P [ X = 1] = 1 − ( n 0) p 0 q n − ( n 1) p 1 q n − 1 = 1 − q n − n p q n − 1 = 1 − ( n + 1) ( 1 2) n.
