In this tutorial I show you how to handle the mean changing over a period of time or space. You are also introduced to using the Cumulative Poisson Distribution Probability tables.

In a certain factory accidents occur at a mean rate of 2 per week. Assuming the number of accidents per week follows a Poisson Distribution, find the probability of less than 3 accidents occurring in a given fortnight.
