The Rivera Family has put up a small business, which sells cakes and pastries. It was observed that the time (in minutes) between order placements follows an exponential distribution with a rate parameter of 1/17. After receiving the first order, what is the probability that the family will have to wait: more than 23 minutes for the next order? at most 14.37 minutes for the next order? between 19.05 and 25.40 minutes for the next order?
