Cumulative binomial distribution function. Returns the probability of k or fewer successes out of n trials, with a probability of success, p for each trial. Note that n and k are integers with k≤n. With the optional fourth arguments k2, returns the cumulative probability for the two k-values; that is, the probability of between k and k2 successes.


BINOMIAL_CDF(20, 0.5, 6) returns 0.05765914917 BINOMIAL_CDF(20, 0.5, 6, 12) returns 0.847717285156
