Let (X,Y) Be uniformly distibuted on the triangle generated by the points (0,0), (1,0) and (0,1). More formally the joing pdf is given by.
FXY(x,y)={2 0
0 otherwise
-check the fact that fX,Y is indeed a valid joint pdf
-Find E(XY)
-Find E(X)
-Find the value of the pX,Y
Find the standard deviation of x
