4.23: Expected Value of Random Variables | Exercise Solution of Probability & Statistics by Walpole

This is the exercise problems solution of the 9th edition of"Probability and Statistics for Engineers and Scientists by Walpole". In this video, I solve exercise problem 4.23 to find the expected value or average value using the joint probability function.
4.23 Suppose that X and Y have the following joint probability function:
(a) Find the expected value of g(X, Y ) = XY2.
(b) Find μX and μY .
