Suppose that a game has the following payoff matrix:

\[
\begin{bmatrix}
5 & -1 \\
-8 & 7 
\end{bmatrix}
\]

Calculate the expected values for the following strategies and determine which of the following situations is most advantageous to R:

(a) R plays \(\begin{bmatrix} 0.5 \\ 0.5 \end{bmatrix}\), C plays \(\begin{bmatrix} 0.5 \\ 0.5 \end{bmatrix}\)

(b) R plays \(\begin{bmatrix} 1 \\ 0 \end{bmatrix}\), C plays \(\begin{bmatrix} 0.5 \\ 0.5 \end{bmatrix}\)

(c) R plays \(\begin{bmatrix} 0.3 \\ 0.7 \end{bmatrix}\), C plays \(\begin{bmatrix} 0.2 \\ 0.8 \end{bmatrix}\)

(d) R plays \(\begin{bmatrix} 0.25 \\ 0.75 \end{bmatrix}\), C plays \(\begin{bmatrix} 0.2 \\ 0.8 \end{bmatrix}\)
