If events occur independely at uniformly distributed random times, the Poisson distribution gives the probabability distribution of the number of events than occur in a given time interval. If on average μ events occur in the time interval the number of actual events that occur is Poisson distributed with parameter μ.

The Poisson distribution has the unusual property that the distribution of a sum of Poisson distributed values itself has a poisson distribution, with a mean equal to the sum of the means of the contributing addends.
