Question
![The image presents a game theory problem asking to convert an extensive form game into normal form to find all pure strategy Nash equilibria.
### Description of the Game Tree:
- **Players**: Two players are involved in this game.
1. **Initial Decision Node (Player 1)**:
- Player 1 starts at the top node and has two options:
- **A**: Leads to the left branch.
- **B**: Leads to the right branch.
2. **Middle Decision Node (Player 2)**:
- If Player 1 chooses A, Player 2 gets a choice between:
- **W**: Results in the payoff (4, 3).
- **X**: Results in the payoff (1, 2).
3. **Middle Decision Node (Player 2)**:
- If Player 1 chooses B, Player 2 gets a choice between:
- **W**: Results in the payoff (3, 1).
- **X**: Results in the payoff (2, 4).
### Explanation of the Diagram:
- **Nodes**: The circles represent decision points for the players.
- **Branches**: Lines leading from nodes show the possible actions available to the player at that node.
- **Payoffs**: The pairs of numbers at the terminal nodes represent the payoffs for Player 1 and Player 2, respectively.
### Goal:
Convert this extensive form into a normal form matrix and identify the pure strategy Nash equilibria. The task involves outlining the strategies and calculating potential outcomes to determine equilibrium conditions in the strategic form of the game.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe68bd869-6397-4145-9644-3499e50efdf3%2F07ebe4dc-1123-48cd-a3c7-1519612292c0%2F1rtj80q_processed.png&w=3840&q=75)
