A pair of random variables (X, Y ) has a joint probability
distribution in which X ∼ U(0, 1), and (Y | X = x) ∼ U(−3x, 5x);
that is, the conditional distribution of Y given {X = x} is uniform
on the interval (−3x, 5x).

3. A pair of random variables (X, Y) has a joint probability distribution in which X ~ U(0,1), and (Y|X = z) ~ U(-3x, 5x); that is, the conditional distribution of Y ; given {X = x} is uniform on the interval (-3x, 5x). = x = (a) Determine the marginal probability density function of Y. (b) Determine EY. (c) Determine the correlation between X and Y. [3 marks] [2 marks [4 marks]
