The computer store sells personal computers (PC's) in two different branches: A and B. Let X be the number of PC's sold per day in branch A and Y the number sold in branch B. Assume that X and Y are independent random variables having the following distributions:. 1 2 p(x) 0.25 0.5 0.25 and 0. 1 p(y) 0.1 0.9 Suppose that net income from selling one PC is $100 in location A and $200 in location B. a) What is the probability that on a given day branch A sells more computers than branch B? b) What is the probability that on a given day branch A and B sell the same number of computers c) What is the expected value and the standard deviation of the total daily net income from computer sales?
