1. (Sec 5.3) Suppose that when you call OIT, the length of time you have to wait on hold before talking to a live person is uniformly distributed on the interval (0,10). Say that you have to call three times this month. Let Y1 be the time you have to wait on hold the first time, Y2 is the time you have to wait the second time you call, and Y3 is the time you spend on hold on the third call. (Note that random samples taken from a common distribution are independent). Let Y = max{Y,Y2,Y3}. Find P(Y < 5).

Question
1. (Sec 5.3) Suppose that when you call OIT, the length of time you have to wait on
hold before talking to a live person is uniformly distributed on the interval (0,10).
Say that you have to call three times this month. Let Y1 be the time you have to
wait on hold the first time, Y2 is the time you have to wait the second time you
call, and Y3 is the time you spend on hold on the third call. (Note that random
samples taken from a common distribution are independent).
Let Y = max{Y,, Y2, Y3}. Find P(Y < 5).
