Suppose the numbers of times that vending machine A and vending machine B are out of order in a month follow Poisson distributions with means 1 and 2 respectively. Find the probabilities that (a) both vending machines A and B are out of order for 3 times in a month, (b) exactly one vending machine is out of order once in a month, (c) both vending machines A and B work properly for 2 consecutive months. (Give your answers correct to 3 significant figures.)
