Exercise 4.1 The number of defects on the front side (X) of a wooden panel and thenumber of defects on the rear side (Y) of the panel are under study.1. Suppose that the joint p.m.fof X and Y is modeled asfx (x, y) = s(x + y), x = 1, 2, 3 and y = 1, 2, 3Determine the value of c.2. Determine the marginal p.m.f. of X. Find also the mean and varianceof X.3. Determine the conditional p.m.f. of Y given X= 2. Find also theconditional mean and conditional variance of Y given X= 2.4. Check if the number of defects on the front side (X) of a wooden paneland the number of defects on the rear side (Y) of the panel areindependent.Engr. A. CUH-ING
