After leaving the kitchen, Tom will return after a random amount of time, which follows an exponential distribution with mean 15 seconds. Suppose Jerry needs 12 seconds to get across the house, and starts immediately after Tom leaves the kitchen. What is the probability that Jerry the mouse will get caught?
