Let X and Y be a continuous random variables defined on the probability space (,E(),P). If the
density function of X is defined by: fXY(x,y)={Ae(x+y),0,0yx,x<otherwise where A>0 is a constant.
1. (5pts) Find the constant A. 2. (10pts) Find the distribution and the density function for X. 3.
(5pts) Compute the probability P[X<2,1<Y]. 4. (5pts) Compute the conditional probability P[X4X>3]
. 5. (10pts) Compute the expected value, E[XY].
