A particular professor never dismisses class early. Let x denote the amount of time past the class end time (in minutes) that elapses before the professor dismisses class. Suppose that x has a uniform distribution on the interval from 0 to 10 minutes. The density curve is shown in the following figure. Density 10 Time (minutes) (a) What is the probability that at most 4 minutes elapse before dismissal? (b) What is the probability that between 4 and 7 minutes...

Suppose you're waiting for train A and your friend train B. Let X denote the wait time for train A, Y the wait time for train B. Both X and Y are in minutes. Suppose that the two wait times have a joint probability density function p(x,y) = 12e-4x-3y. Suppose you're only willing to wait one hour for a train. What is the probability that you'll board your train after your friend boards hers? What is the probability that train...
