Let $ X $ be a random variable with PMF as \begin{tabular}{|c|c|c|c|} \hline$ x $ & 0 & 2 & 3 \\ \hline$ f_{X}(x) $ & $ 1 / 5 $ & $ 3 / 5 $ & $ 1 / 5 $ \\ \hline \end{tabular} Suppose $ X_{1}, X_{2} \sim $ i.i.d. $ X $. Define a random variable $ Y=X_{1}+X_{2} $. Based on the given information, answer the follwing sub-questions. 12) Which of the following option(s) is (are) true? $ M_{Y}(\lambda)=M_{X_{1}}(\lambda) \times M_{X_{2}}(\lambda) $ $ M_{Y}(\lambda)=M_{X_{1}}(\lambda)+M_{X_{2}}(\lambda) $ $ M_{Y}(\lambda)=\left(M_{X}(\lambda)\right)^{2} $ $ M_{Y}(\lambda)=\frac{1}{25}+\frac{6}{25} e^{2 \lambda}+\frac{2}{25} e^{3 \lambda}+\frac{9}{25} e^{4 \lambda}+\frac{6}{25} e^{5 \lambda}+\frac{1}{25} e^{6 \lambda} $ $ M_{Y}(\lambda)=\frac{1}{25}+\frac{6}{25} e^{2 \lambda}+\frac{h_{5}^{9}}{25} e^{4 \lambda}+\frac{6}{25} e^{5 \lambda}+\frac{1}{25} e^{9 \lambda} $ 13) Calculate $ E[Y] $.
