A and B are two competing companies. An investor decides whether to buy (a) 100 shares of A, or (b) 100 shares of B, or (c) 50 shares of A and 50 shares of B. A profit made on 1 share of A is a random variable X with the distribution P(X = 2) = P(X = −2) = 0.5. A profit made on 1 share of B is a random variable Y with distribution P(Y=4)=0.2 and P(Y=-1)=0.8
If X and Y are independent, compute the expected value and variance of the total profit for strategies (a,) (b,) and (c.)
