Which of the following is/are true?If X and Y are independent, then fx(x) 2 0, fy(y) 2 0, and fx y(x, y) = fx(x) fy(y) for all values of x & y.Regardless of whether X and Y are independent, fx(x) s 0, fy(y) s 0, and fx y(x, y) 2 0 for all values of x & y.If X and Y are positively correlated, then fx y(x, y) < fx(x) fy(y) for all values of x & y.If X and Y are negatively correlated, then fx y(x, y) < fx(x) fy(y) for all values of x & y.
