Poisson Distribution - Changing the Mean
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 occuring in a given fortnight.
