The cdf for the binomial distribution with n trials, probability p of success for each trial, and k successes.
The probability of getting k successes out of n trials if the probability is p.
Returns the cumulative distribution function at x for the hypergeometric distribution with population size N, K items in the category of interest, sample size n, count of interest x, and optional odds ratio r.
Returns the probability that a negative binomially distributed random variable is less than or equal to k, where the probability of success is p and the number of successes is n.
Returns the probability that a negative binomially distributed random variable is equal to k, where the probability of success is p and the number of successes is n.
Returns the cumulative distribution function at k for the Poisson distribution with mean lambda.
