2.2.4 Suppose we roll one fair six-sided die, and let Z be the number showing. Let W = Z3 + 4, and let V = Z. (a) Compute P(W = w) for every real number w. (b) Compute P(V = v) for every real number v. (c) Compute P(ZW = x) for every real number x. (d) Compute P(VW = y) for every real number y. (e) Compute P(V + W = r ) for every real number r.
