How to solve joint probability
WebFirst we identify the part L of the plane where the joint density function of X and Y "lives." Draw the vertical lines x = 1 and x = 2. Draw the line y = x. The joint density lives on the part L of the first quadrant that is between x = 1 and x = 2, and below y = x. This region L is a trapezoid with corners ( 1, 0), ( 2, 0), ( 2, 2), and ( 1, 1).
