A payoff table is shown below. $\begin{array} { ccc }&\text { Alternative }\\\text { State of Nature }& a_{1} & a_{2} & a_{3}\\s_{1} & 21 & 8 & -3 \\s_{2} & 12 & 12 & 7 \\s_{3} & -15 & 9 & 13\end{array}$
The following prior probabilities are assigned to the states of nature:
P( $S _ { 1 }$ ) = 0.2, P( $S _ { 2 }$ ) = 0.7, P( $S _ { 3 }$ ) = 0.1.
a. Determine the EMV decision.
b. Set up the opportunity loss table.
c. Determine the EOL decision.
