What is a Binomial Distribution?

Back

A Binomial Distribution models the number of successes in a fixed number of independent Bernoulli trials, each with the same probability of success.

What is a Geometric Distribution?

Back

A Geometric Distribution models the number of trials needed to get the first success in a series of independent Bernoulli trials.

When would you use a Binomial Distribution?

Back

Use a Binomial Distribution when you have a fixed number of trials, each with two possible outcomes (success or failure), and you want to find the probability of a certain number of successes.

When would you use a Geometric Distribution?

Back

Use a Geometric Distribution when you are interested in the number of trials until the first success occurs.

What is the formula for Binomial Probability?

Back

P(X = k) = (n choose k) * p^k * (1-p)^(n-k), where n is the number of trials, k is the number of successes, and p is the probability of success.

What is the formula for Geometric Probability?

Back

P(X = k) = (1-p)^(k-1) * p, where k is the trial on which the first success occurs and p is the probability of success.
