(10 pts.) A group of people at a hotel are going to dinner and need three cabs to get them to the restaurant. The arrival time for an empty cab has an exponential distribution with mean 1.5 minutes. Assuming the cabs operate independently, what is the probability that it will take the group more than 5 minutes to hail all 3 cabs? Explain your answer. (Hint: Consider the question, "Is the arrival time for 3 cabs equal to the sum...
