What is Negative Binomial Distribution?

The Negative Binomial Distribution is a probability distribution for a discrete random variable that describes the number of Bernoulli trials (experiments with only two possible outcomes, such as success or failure) that must be conducted in order for a given number of successes to occur.
The probability of success in each trial is denoted as "p" and the number of successes is denoted as "r". The probability mass function of the negative binomial distribution is given by: P(X = k) = (k-1+r)C(r-1) *(p^r)*((1-p)^(k-r))

The Negative Binomial Distribution is a generalization of the geometric distribution, which corresponds to the case when r=1. It is used in modeling the number of failures before a given number of successes in a sequence of Bernoulli trials.
