For the random variables X and Y whose joint density function is given in Exercise 2.32 on page 72, find the covarianc

Exercise 2.32

A fast-food restaurant operates both a drive through facility and a walk-in facility. On a randomly selected day, let X and Y, respectively, be the proportions of the time that the drive-through and walk-in facilities are in use, and suppose that the joint density function of these random variables is

{(x+ 2y), (0, 0< r< 1, 0 < y < 1, elsewhere. f(x, y) =

{(x+ 2y), (0, 0 < r < 1, 0 < y < 1, elsewhere. f(x, y) =
