Problem #11: Suppose that a discrete random variable $X$ has the following probability mass function, $$ \begin{array}{cccc} X & 1 & 4 & 6 W p(x) & \frac{1}{10} & \frac{1}{20} &\frac{17}{20) \end{array} $$ Find the moment generating function. Problem #11: Enter your answer as a symbolic function of $t$, as in these examples SP.VS. 887
