Enter the number of trials, number of successes, and probability of success on trial into the calculator to determine the negative binomial.

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.

Negative Binomial Example

How to calculate a negative binomial?

  1. First, determine the number of successes.

    Measure the total number of successes.

  2. Next, determine the total probability of success.

    Calculate the probability of success.

  3. Finally, calculate the negative binomial.

    Calculate the negative binomial using the formula above.


What is a negative binomial?

Also known as pascal distribution, a negative binomial distribution is a probability solution that models the number of successes in a sequence of Bernoulli trials.
