TASK: suppose that we are investigating the safety of a dangerous intersection past police records indicate a mean of five accidents per month at this intersection. The number of accidents is distributed according to a Poisson distribution, and the Highway Road Safety Division wants us to calculate the probability in any month of exactly 0, 1, 2, 3, or 4 accidents. Hint: A 5
