Let X and Y be independent random variables. 1. Are X and -Y independent? (Hint: Use Theorem: Let X₁, X2, Xn be mutually independent continuous random variables and let 1(x), 2(x),.., n(x) be continuous functions. Then 01(X1), 02(X2),.., n(Xn) are mutually independent.) 2. Either prove V(X+Y) = V(X - Y), or provide a counterexample.
