What is a Binomial Random Variable?

Back

A Binomial Random Variable is a discrete random variable that counts the number of successes in a fixed number of independent Bernoulli trials, each with the same probability of success.

What are the parameters of a Binomial Distribution?

Back

The parameters of a Binomial Distribution are 'n' (the number of trials) and 'p' (the probability of success on each trial).

What is the difference between a Binomial and a Geometric Distribution?

Back

A Binomial Distribution counts the number of successes in a fixed number of trials, while a Geometric Distribution counts the number of trials until the first success.
