Let X be the arrival time in minutes of the next red traffic light on a certain delivery route. We model X using the exponential distribution with parameter A = 0.2 red traffic lights per minute, X~Exp(0.2). (a) Calculate the probability that we drive for 2 minutes or more with no red traffic lights. (b) On average, how long can we drive with no red traffic lights?
