1. Let fx,y(x, y) k if - 1

1. Let = be the joint density function of random O otherwise variables r, Y where k O. Do the following problems (a) (b) (c) (d) Draw and shade the region for which fx,Y 0 Compute the value of k Compute i.e. the marginal density of X. Compute y) i.e. the conditional density function of Y given X.
