Binomial Probability Distribution

A probability distribution that summarizes the likelihood that a variable will take one of two independent values under a given set of parameters or conditions.

Binomial Problem

A statistical question or experiment that has exactly two possible outcomes, 'success' or 'failure', and where the probability of success is the same each time the experiment is conducted.
