It is known that the shelf life of refills for a certain brand of purifier of water is exponentially distributed with an average of 3 years. Joe has already used his refill from said brand for 2 years in a row. What is the probability that Joe does not need change your water purifier refill in the next 2 years?

At a bank, there is a line of 3 people and only one cashier that serves one person at a time. The time that the cashier takes to serve each person has an exponential distribution with a mean of 5 minutes. Calculate the probability that the total time of serving the 3 people is less than 15 minutes. Assume that the serving times are independent.
