1.1 Solve the below problem: (10) Let Y, and Yz denote the proportions of time (out of one workday) during which employees I and II, respectively, perform their assigned tasks. The joint relative frequency behaviour of Y, and Yz is modelled by the density function f(1, y2 ) = Syityz Ogyis1,0s y21, 0, elsewhere. 1.1.1. Find P(Y, . Yz > >). (2) 1.1.2. The marginal density function of Yz is f2(12) = 12+5 0
