Customers arrive at a pet store at a rate of 3/hr. The number of customers between Dog-buyers Y satisfies P (Y = i − 1) = 1/3 (2/3)^(i − 1), i = 1, 2, 3,... meaning, if customer c buys a dog, then the probability the next Dog-buying customer is customer (c + i) is 1/3 (2/3)^(i − 1). Of those that buy dogs, 1/4 buy Cockapoos. What is the probability that 5 Cockapoos will be sold in a 12...
