Five friends go out to a pub together. They agree to let a roll of the dice determine who pays for each round. Each friend rolls one die, and the one getting the lowest number of points picks up the tab for that round. If the low number is rolled by more than one friend in any given round, then the tab will be divided among them. At a certain point in the evening, one of the friends decides to go home; however, rather than withdraw from the game he proposes to participate in absentia, and he is assigned a point value of 2½. Afterward, he will be responsible for paying up on the rounds he lost, calculating in an amount for the rounds he won. Is this a fair deal?
