negative_binomial_distribution in C++ with Examples

This function is defined in header randomRandom. Negative binomial distribution is Random number distribution that produces integers according to a negative binomial discrete distribution (also known as Pascal distribution), which is described by the following probability mass function. 

The value represents the number of failures in a series of independent yes/no trials (each succeeds with probability p), before exactly k successes occur.
