![]() Just like the Binomial Distribution, the Negative Binomial distribution has two controlling parameters: the probability of success p in any independent test and the desired number of successes m. The mean, variance, and standard deviation for a given number of successes are represented as. In contrast, for a negative binomial distribution, the variance is greater than the mean. With the Poisson distribution, on the other hand, variance and mean are equal. ![]() How many cards will I have to draw from a pack until I get the second Joker? For a binomial distribution, variance is less than the mean.The number of extra trials you must perform in order to observe a given number. ![]() The simplest motivation for the negative binomial is the case of successive random trials, each having a constant probability P of success.
