## Negative Binomial Formula

The following formula can be used to calculate the negative binomial of distribution.

P = k*(1-p)/p

- Where P is the negative binomial
- p is the probability of success
- k is the number of success

## Negative Binomial Definition

A negative binomial, or pascal distribution, is the probability that the solution of some statistical model will behave the same number of successes in a sequence as a Bernoulli trial.
