Unformatted text preview: D 1 , D 2 , and D 3 be the distances of the darts to the center of the dartboard (so 0 ≤ D i ≤ 1), and let ≤ D (1) ≤ D (2) ≤ D (3) ≤ 1 be the corresponding order statistics. Find E ( D (2) ) and the joint density of D (1) and D (3) . 4. Ten men and ten women are randomly seated around a round table. Let N be the number of men whose immediate neighbors are both women. Find EN , P ( N = 10), P ( N = 9). 5. Find a function f : R 2 → R 2 such that if U 1 and U 2 are independent uniform (0 , 1) random variables then f ( U 1 ,U 2 ) is uniformly distributed on the triangle { ( x,y ) : 0 ≤ x ≤ 2 , ≤ y ≤ x } ....
