Suppose that X and Y are statistically independent and identically distributed uniform random variables on (0,1).
(a) Write down the joint probability density function fxy(x,y) of X and Y on its support.
Answer:
(b) The expression for the joint probability density function of the transformed random variables U = 5X + Y and V=7X+2 Y on its support is:
fu,v(u,v) = A B (C v+ D) E
