This form of sum is a poisson generating function, which can also be framed in more common parlance as an exponential generating function: The probability of less than 2 indicates the first possibility of zero accidents and the second possibility of one accident.

The poisson distribution has the parameter , which indicates the mean rate of occurrence of events. P ( x) = e − λ ⋅ λ x x! From probability generating function of poisson distribution:

In 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 Or Space If These Events Occur With A Known Constant Mean Rate And Independently Of The Time Since The Last Event.

In exponential distribution, it is the same as the mean. Cumulative distribution function of the poisson distribution is, where is the floor function. To calculate the mean of a poisson distribution, we use this distribution's moment generating function.

It is named after french mathematician siméon denis poisson (/ ˈ p w ɑː s ɒ n. The poisson distribution is a discrete distribution under which the random variable counts the number of events occurring in a specified time interval. Therefore, the expected value (mean) and the variance of the poisson distribution is equal to λ.
