1. Suppose that the joint p.m.f of X and Y is modeled as fro (x, y) = c(x + y), x = 1, 2, 3 and y = 1, 2, 3 Determine the value of c. 2. Determine the marginal p.m.f of X. Find also the mean and variance of X. 3. Determine the conditional p.mf of Y given X= 2. Find also the conditional mean and conditional variance of Y given X= 2. 4. Check if the number of defects on the front side (X) of a wooden panel and the number of defects on the rear side (Y) of the panel are independent.
