To find the expected value of this probability distribution, we can use this expression:

$\begin{gathered} E(x)=\sum ^{}_{}x\cdot p \\ E(x)=(2)((1)/(36))+(3)((1)/(18))+(4)((1)/(12))+(5)((1)/(9))+(6)((5)/(36))+(7)((1)/(6))+(8)((5)/(36))+(9)((1)/(9))+(10)((1)/(12))+(11)((1)/(18))+(12)((1)/(36)) \end{gathered}$

Solving this E(x) is equal to:
