Hello, I need help with the following question. Please be sure
to answer part A and B.

Show transcribed image text X and Y are independent exponential r.v.' with parameters b and d respectively. It is impossible to observe X and Y. Instead we can observe r.v.'s Z and W, where Z = min(X, Y) and W = {1, if Z = X 0, if Z = X This is the situation that arises, in particular, in medical experiments. Both X and Y are censored. a. Find the joint distribution of Z and W. b. Prove that Z and W are independent. (hint: show that P(Z
