Extracted text: Fast food restaurants spend quite a bit of time studying the amount of time cars spend in their drive-throughs. Survey found Burger King had the best time, with a mean time spent in the drive-through of 138.5 seconds. Assuming drive-through times are normally distributed with a standard deviation of 29 seconds, answer the following questions. a) Compute the probability that a randomly selected car will get through Burger King's drive-through in less than 100 seconds. b) Compute the probability that a randomly selected car will spend more than 160 seconds in Burger King's drive-through. c) Compute the probability of cars spends between 2 and 3 minutes in Burger King's drive-through.
