Poisson distribution - Wikipedia
WEBIn probability theory and statistics, the Poisson distribution 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.

WEBMay 13, 2022 · A Poisson distribution is a discrete probability distribution. It gives the probability of an event happening a certain number of times ( k ) within a given interval of time or space. The Poisson distribution has only one parameter , λ (lambda), which is the mean number of events.

WEBA Poisson distribution measures how many times an event is likely to occur within “x” period of time. In other words, we can define it as the probability distribution that results from the Poisson experiment.
