Question: Suppose that a point (X, Y) is chosen at random from the circle S defined as follows: S = {(x, y): x2 + y2

Suppose that a point (X, Y) is chosen at random from the circle S defined as follows:
S = {(x, y): x2 + y2 ≤ 1}.
a. Determine the joint p.d.f. of X and Y, the marginal p.d.f. of X, and the marginal p.d.f. of Y.
