Either a mixed column or mixed row strategy is given. Use the given payoff matrix and find the optimal pure strategy (or strategies) the other player should use. Express the answer as a row or column matrix. Also determine the resulting expected payoff.

The text appears to provide instructions related to game theory, specifically involving strategies and payoff matrices. Here's a breakdown suitable for an educational website:

**Game Theory Strategy Analysis**

In this exercise, we analyze either a mixed column or mixed row strategy using a given payoff matrix. The goal is to identify the optimal pure strategy (or strategies) the other player should use. The answer should be expressed as either a row or column matrix, and the resulting expected payoff should be determined.

**Payoff Matrix (P):**

\[ 
P = \begin{bmatrix} 
0 & -1 & 5 \\
2 & -2 & 4 \\
0 & 3 & 0 \\
1 & 0 & -5 
\end{bmatrix}
\]

**Task a:**

Given a mixed strategy column vector \( C \), defined as:

\[ 
C = \begin{bmatrix} 
\frac{1}{3} \\ 
\frac{1}{3} \\ 
\frac{1}{3} 
\end{bmatrix}^T 
\]

Determine the optimal strategy for the row player and the expected payoff.

**Task b:**

Given a mixed strategy row vector \( R \), defined as:

\[ 
R = \begin{bmatrix} 
0.8 & 0.2 & 0 & 0 
\end{bmatrix}
\]

Determine the optimal strategy for the column player and the expected payoff.

For each part, students should calculate the expected payoffs by using the strategies provided and find the best response for the opposing player based on the payoff matrix. Students should apply concepts of mixed strategies and expected values to solve the problem.
