A chemical supply company currently has in stock 100 Ib of a certain chemical, which it sells to customers in 3-lb batches. Let X = the number of batches ordered by a randomly chosen customer, and suppose that X has the 3 4 p(x) 0.3 0.5 0.1 0.1 Compute E(X) and V(X). batches E(X) = V(X) = batches? Compute the expected number of pounds left after the next customer's order is shipped and the variance of the number of pounds left. [Hint: The number of pounds left is linear function of X.) expected weight left Ib variance of weight left Ib2
