A fair red die and a fair blue die are rolled. Let X be the random variable for the number on the red die and Y be the random variable for the number on the blue die. Evaluate the expected value of the difference of these two random variables, i.e., E((X-Y)).

Solution
E(X-Y)=E(X)-E(Y)=0 As E(X) = E(Y) As both are the random variable giving number coming the die.
