Suppose we roll a die, let X be the number we get. Suppose p(x) = P(X = 2) is such that p(1).1, p(2) = .1, p(3) = .1, p(4) = .2, p(5) = .2, p(6) = .3. (1) Calculate E(X) and Var(X). == == (2) Suppose the reward for x is h(x), and h(1) = $20, h(2) = $10, h(3) = 80, h(4) = $10, = h(5) $20, h(6) = $100. Calculate E(h(X)) and Var(h(X)). What are the units of E(h(X)) and Var(h(X))? Suppose we roll a die, let X be the number we get. Suppose p(x) = P(X = 2) is such that p(1).1, p(2) = .1, p(3) = .1, p(4) = .2, p(5) = .2, p(6) = .3.
