Function rgsl::randist::binomial::binomial

pub fn binomial(r: &mut Rng, p: f64, n: u32) -> u32

This function returns a random integer from the binomial distribution, the number of successes in n independent trials with probability p. The probability distribution for binomial variates is,

p(k) = {n! \over k! (n-k)! } p^k (1-p)^{n-k}

for 0 <= k <= n.
