What Does the Binomial Distribution Formula Do

What does the binomial distribution formula do?

A) It computes the number of permutations of x successes (and, therefore, n - x failures) that can be achieved in n trials of a random experiment that satisfies the conditions of the binomial experiment.
B) It computes the probability of x successes in n trials of a random experiment that satisfies the conditions of a binomial experiment.
C) It produces one of two possible outcomes, conventionally called success and failure.
D) It produces the probability of x successes when a random sample of size n is drawn without replacement from a population of size N within which M units have the characteristic that denotes success.
