Questiоn 4 (15pts) Independent rаndоm vаriаbles X and Y bоth takes the values {0, 1}, and are defined on the same probability space such that Pr[X = 1] = Pr[Y = 1] = 1/2. Consider the random variables Z = (1 − X)(1 − Y ) and W = 1 − XY . (a) Among Z and W, which one has the larger expectation? Justify your answer. (b) Among Z and W, which one has the larger variance? Justify your answer. (c) Are Z and W independent? Justify your answer.
