Joe knows from experience that on average it takes thirty-five minutes to mow his yard. He really needs to mow the yard, but the big game kicks-off in forty-five minutes and he really wants to see that too. His DVR is not working and he really needs to mow that yard. If he starts right now, what is the probability that he can finish mowing the yard before the start of the game? Draw the graph that would illustrate this problem and compute the probability assuming that yard mowing follows an exponential distribution.
