Problem 4 (15 points): The joint pmf of two random variables, \( X \) and \( Y \), is given by \[ p_{X, Y}(x . y)=\left\{\begin{array}{l} \frac{1}{3} \text { for }(x . y) \in\{(0,1),(1,0),(2,1)\} \\ 0 \text { otherwise } \end{array}\right. \] (a) Are \( X \) and \( Y \) independent? (b) Are \( X \) and \( Y \) uncorrelated?
