What must you know to develop a binomial probability distribution?

Answer by  Mac44 (479)

Most importantly, you must know that the distribution actually stems from one of a set of choices. In other words, there is a set, limited probability from which the distribution can come from. This could be flipping a coin or even a 12-sided die. From there, you must know the probability of each occurrence, number of "flips", and "k" successes.

You only need to know the probability of a successful outcome in one trial (p) , and the total number of trials (n). The formula for the binomial distribution is P(x)= (n! /x! (n-x)! ) * p^x * (1 - p) ^(n-x), where x = number of successes.
