Definitions:

Binomial 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.

Independent Trials

Independent Trials are experiments or processes in which the outcome of any given trial does not affect the outcome of any other trial.

Poisson Distribution

A probability distribution that measures the probability of a given number of events happening in a fixed interval of time or space.
