Let Y1 and Y2 denote the proportions of time (out of one workday) during which employees I and II, respectively, perform their assigned tasks. The joint relative frequency behavior of Y1 and Y2 is modeled by the density function f (y1, y2) = y1 + y2, 0 y1 1, 0 y2 1, 0, elsewhere. a Find P(Y1 < 1/2, Y2 > 1/4). b Find P(Y1 + Y2 1)
