2. A fast-food restaurant operates both a drive-through facility and walk-in facility. On a randomlyselected day, let X and Y, respectively, be the proportion of the time that the drive-thorugh and walk-in facilities are in use, and suppose that the joint density function of these random variables isf(x,y) = }3(x + 2y), 0
