A 12-in. bar that is clamped at both ends is to be subjectedto an increasing amount of stress until it snaps. LetY 5 the distance from the left end at which the breakoccurs. Suppose Y has pdff(y) 5 511242y11 2 y122 0 # y # 120 otherwiseCompute the following:a. The cdf of Y, and graph it.b. P(Y # 4), P(Y . 6), and P(4 # Y # 6)c. E(Y), E(Y2), and V(Y)d. The probability that the break point occurs more than2in. from the expected break point.e. The expected length of the shorter segment when thebreak occurs.
