Notes on the Negative Binomial Distribution

WebThe binomial distribution formula is for any random variable X, given by; P (x:n,p) = n C x p x (1-p) n-x Or P (x:n,p) = n C x p x (q) n-x. Where p is the probability of success, q is the probability of failure, and n = number of trials. The binomial distribution formula is also written in the form of n-Bernoulli trials.
