A bus is supposed to arrive at a given bus stop at 10:00 a.m., but the actual time of arrival is a r.v. X which is uniformly distributed over the 16-minute interval from 9:52 to 10:08. If a passenger arrives at the bus stop at exactly 9:50, what is the probability that the passenger will board the bus no later than 10 minutes from the time of his/her arrival?
