Cumulative distribution function cdf calculator for the binomial distribution. In a binomial distribution the probabilities of interest are those of receiving a certain number of successes, r, in n independent trials each having only two possible outcomes and the same probability, p, of success. Statistics and machine learning toolbox also offers the generic function pdf, which supports various probability distributions. Since the binomial applies as there is a fixed number of trials, the probability of success is the same for each trial, and there are only two outcomes for each trial.
