Suppose the joint probability density function for the random variables XXX and YYY is
f(x,y)={xe−x−y if x≥0 and y≥00 otherwise f(x, y)= \begin{cases}x e^{-x-y} & \text { if } x \geq 0 \text { and } y \geq 0 \\ 0 & \text { otherwise }\end{cases} f(x,y)={xe−x−y0 if x≥0 and y≥0 otherwise
Find the probability that (X,Y)(X, Y)(X,Y) lies in the rectangular region RRR with vertices (0,0),(1,0),(0,2)(0,0),(1,0),(0,2)(0,0),(1,0),(0,2), and (1,2)(1,2)(1,2).
