A depanneur orders copies of a certain magazine for its magazine rack each week. Let the demand for the magazine be X and suppose the probability distribution of X is: X: 1 2 3 4 5 P(X): 1/10 1/5 1/4 1/5 1/10 a) Calculate the expected value E(X) and variance V(X). b) Suppose the store owner actually pays $2.00 for each copy of the magazine and the price to customers is $4.00. If the owner orders six copies of the magazine and copies left unsold at the end of the week are wasted, express the net revenue Y as a function of the demand X and find the expected net revenue E(Y) and variance V(Y).
