The Poisson Probability Distribution
... If cars arrive at McDonald’s at the rate of 2 per minute between 12:00 noon and 1:00 p.m., how many cars would you expect to arrive between the hours of 12:00 noon and 12:05 p.m.? Considering that 2 cars arrive every minute (on average) and we are observing the arrival of cars for 5 minutes, it migh ...
