unsigned cmb_random_negative_binomial(unsigned m, double p)

Negative binomial distribution, the number of failures before the mth success in independent Bernoulli trials each with probability p, sampled with replacement (or equivalently from an infinite pool).

Mean m(1-p)/p, variance m(1-p)/p^2. Equal to a geometric distribution for m = 1.

Used to model e.g., the number of bits (or packets) that need to be sent to successfully transmit an m-bit (or -packet) message. Also known as the Pascal distribution.

Performs the calculation by simulating the experiment.
