Can you please show working for example - find: E(XY)

Can you please show working for example - find: E(XY) Properties of

Properties of conditional expectation & variance Examples > E(X|X) = X , E(X|Y) 2 BY + 5 and Y~N(1,2). > E(f(Y)X|Y) = f(Y)E(X|Y) , Find E(XY) > If X and Y are independent, then E (X |Y) = E (X) > E (X) = E [E (X |Y)] (iterated expectation) > Var(X) = E[Var(X|Y)] + Var[E(X|Y)]
