Is this correct?

1). X and Y are independent standard exponential random variables with = 1

(a) FindI did(b) Find(2) A random point (X,Y) is distributed uniformly on the square with vertices (1,1), (1,-1), (-1,1), and (-1,-1). The joint pdf is on the square.I am unsure about this. Any help?

(a) Find

(b) Find

If someone can just teach me how to do one of the above in (2), I think I can handle the other. Thank you!!
