1. A bank operates a drive-up and walk-up window. Let X = the proportion of the time the drive-up facility is in use and let Y = the proportion of the time the walk-up window is in use. Suppose the operations manager uses the following distribution as the joint pdf based on his historical data: f(x, y) = 5 = { 2(x + y²) if 0 (x + y²) if 0 ≤ x ≤ 1 and 0 ≤ y ≤1 otherwise (a) Find the marginal pdf for X, fx(x). (b) Find the marginal pdf for Y, fy(y).

1. A bank operates a drive-up and walk-up window. Let X = the proportion of the time the
drive-up facility is in use and let Y = the proportion of the time the walk-up window is in
use. Suppose the operations manager uses the following distribution as the joint pdf
based on his historical data:
f(x, y) = 5
- 1/2(x + y²) if
0
(x + y²) if 0 ≤ x ≤ 1 and 0 ≤ y ≤1
otherwise
(a) Find the marginal pdf for X, fx(x).
(b) Find the marginal pdf for Y, fy(y).
