The Poisson distribution
(Siméon Denis Poisson,
17811840) can be obtained from the binomial distribution:
let the number of events N go to infinity, where the most probable number of successes
remains constant ^{1)}. We can use the Poisson distribution in the case of a discrete probability process, with a constant frequency. Examples can be found in nuclear physics while counting elementary particles. notes 1) product of n and p, denoted as: a.
