The binomial distribution gives the discrete probability distribution

$P_p(s|n)$

(1)

of obtaining exactly s successes out of n Bernoulli trials (where the result of each Bernoulli trial is true with probability p and false with probability <em>1-p</em>). The binomial distribution is therefore given by:

$P_p(s|n) = \frac{n!}{s!(s-n)!} p^s (1-p)^{n-s}$
