What Wikipedia says

In probability theory and statistics, the Poisson distribution (US: pwahss-ON, UK: PWA(H)SS-on) is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time if these events occur with a known constant mean rate and independently of the time since the last event.
