Defined in header <random>
template< class IntType = int >
class poisson_distribution;
 (since C++11)

Produces random non-negative integer values i, distributed according to discrete probability function:

P(i|μ) =
e-μ·μi
i!

The value obtained is the probability of exactly i occurrences of a random event if the expected, mean number of its occurrence under the same conditions (on the same time/space interval) is μ.
