Transcribed Image Text:(f) Calculate \( E(X|Y = y) \), \( y = 1, 2 \) and calculate \( E(E(X|Y)) \).
(g) Compare \( E(X) \) and \( E(E(X|Y)) \).
(h) Calculate the m.g.f. \( M_{X,Y} \).
![The joint probability density function (p.d.f) of the random variables (r.v.'s) X and Y is given in the following table:
\[
\begin{array}{c|cccc}
y\setminus x & 0 & 1 & 2 & 3 \\
\hline
1 & \frac{1}{8} & \frac{1}{16} & \frac{3}{16} & \frac{1}{8} \\
2 & \frac{1}{16} & \frac{1}{16} & \frac{1}{8} & \frac{1}{4} \\
\end{array}
\]
Explanation:
- The table represents the joint probability density function of the discrete random variables X and Y.
- The columns represent the values of variable X: 0, 1, 2, and 3.
- The rows represent the values of variable Y: 1 and 2.
- Each cell in the table shows the joint probability for a specific pair of (X, Y) values.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa7ffb148-54c7-4dce-915c-269933801524%2F0a1c34b9-668f-4a34-88f0-dc7be7194930%2Fmfnyyj_processed.png&w=3840&q=75)
