Question

Exercise 4.41. We roll a die 72 times. Approximate the probability of getting exactly 3 sixes with both the normal and the Poisson approximation and compare the results with the exact probability .000949681.

(Answers provided in textbook are: Exact: .00095 Poisson: .0018 Normal: .0023)

Answer #1
