## 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 or 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 the 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

The payoff matrix is

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

Anna |
Help | Leave | |

Help | 24, -81 | 96, -66 | |

Leave | -44, -53 | -94, -97 |

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

Ben's payoff is -66.
