一摩尔（NA）相同的徒步旅行者从日内瓦出发，穿过山脉前往地中海。在他们开始之前，他们必须从一堆2NA左右靴子中挑选他们的登山靴。他们都急于离开，每个人从堆中随机挑选一双，结果大约NA/4的徒步旅行者有两只左脚靴子，NA/4的人有两只右脚靴子，剩下的人有一只左脚和一只右脚靴子。显然，对于其中一半人来说，步行是一件痛苦的事情，他们永远不会在晚餐时间之前到达第一个山间小屋，所以他们开始交易。过了一段时间，每个人都有一双合适的靴子（一左一右），现在很容易去，他们都及时到达一个服务的tartiflettes，美味的当地奶酪和土豆烤面包。
One mole (NA) of identical hikers starts from Geneva for a trip through the mountains to the Mediterranean Sea. Before they start, they have to pick their mountain boots from a heap of 2NA left and right boots. They are in a hurry to leave, and each one picks a pair at random from the heap, resulting in approximately NA/4 hikers with two left boots, NA/4 who have two right boots, and the remaining ones who have one left and one right boot. Obviously for half of them walking is a painful affair and they are never going to make it to the first mountain hut before dinner time, so they start trading. After a while everyone ends up with a proper pair of boots (one left and one right), the going is now easy, and they all arrive in time for a serving of tartiflettes, the tasty local cheese and potato gratin.
