The Poisson distribution is a discrete probability distribution that expresses the probability of a given number of events occurring within a fixed interval of time or space, assuming these events occur with a known constant mean rate and independently of the time since the last event. It is particularly useful for modeling the number of times an event occurs in a specific interval when the events happen independently.
