Exercise 5 Trafc accidents at a particular intersection in Campustown follow a Poisson distribution with an average rate of 1.4 per week. [3] Find the exact calculation using the Poisson distribution for the probability that there would be exactly '70 accidents at this intersection in one year [i.e., 52 weeks]. [b] Find an approximation using the Normal distribution for the probability that there would be exactly '70 accidents at this intersection in one year [i.e., 52 weeks]
