Step 1
The joint distribution represents the probability of each possible combination of values for X and Y. Now, the statement says that the joint distribution is always constant. This means that the probability of each combination of values for X and Y remains the Show more…

Random variables $X$ and $Y$ follow a joint distribution $$ f(x, y)=\left\{\begin{array}{ll} 2, & 0<x \leq y<1, \\ 0, & \text { otherwise. } \end{array}\right. $$ Determine the correlation coefficient between $X$ and $Y$

Variance and Covariance of Random Variables
The joint CDF of random variables X and Y is given by: Fxy(x,y) = 0, x < 0 or y < 0 Fxy(x,y) = xy, 0 ≤ x ≤ 1, 0 ≤ y ≤ 1 Fxy(x,y) = x, 0 ≤ x ≤ 1, y > 1 Fxy(x,y) = y, 0 ≤ y ≤ 1, x > 1 Fxy(x,y) = 1, x ≥ 1, y ≥ 1
