## Example

A horde of zombies is attacking the village where Anna and Ben live.

Anna can help or leave the village. Ben can also either help of leave the village.

They would rather be together: help together or leave together. The situation is summarized in the payoff matrix:

Ben | |||
---|---|---|---|

Anna |
Help | Leave | |

Help | 3, 2 | 0, 0 | |

Leave | 0, 0 | 2, 1 |

If Anna Leaves the village and if Ben Leaves village, the corresponding outcome (Leave, Leave) in the matrix is

Ben | |||
---|---|---|---|

Anna |
Help | Leave | |

Help | 3, 2 | 0, 0 | |

Leave | 0, 0 | 2, 1 |

Anna's payoff is 2. Ben's payoff is 1.

### Question

Consider the following payoff matrix:

Ben | |||
---|---|---|---|

Anna |
Help | Leave | |

Help | 60, -58 | -67, 87 | |

Leave | 48, 100 | 89, -68 |

What is Anna's payoff if Anna chooses to Leave and Ben chooses to Leave?

Anna's payoff is 89
