The Fairness Game —Fiorenza

The answer lies in monkeys, rocks, cucumbers and grapes.

Consider the likely results of a classic party game. You are given 10 $5 bills and asked to share them with someone you’ve never met. You are given one chance to decide how much money to share. If your new acquaintance agrees, you both get to keep the amount to which you both agreed. If not, neither of you get anything.
