At a family reunion were the following people: one grandfather, one grandmother, two fathers, two mothers, four children, three grandchildren, one brother, two sisters, two sons, two daughters, one father-in-law, one mother-in-law, and one daughter-in-law.

On the counter are six squares marked 1, 2, 3, 4, 5, 6. Players are invited to place as much money as they wish on any one square. Three dice are then thrown.
1 If your number appears on one die only, you get your money back plus the same amount.
1 If two dice show your number, you get your money back plus twice the amount you placed on the square.
1 If your number appears on all three dice, you get your money back plus three times the amount.
1 If the number is not on any of the dice, the operator gets your money.
For example, suppose that you bet one Rupee on square No. 6. If one die shows a 6, you get your Rupee back plus another Rupee. If two dice show 6, you get back your Rupee plus two Rupees. If three dice show 6, you get your Rupee back plus three Rupees.
From a player’s point of view, the chance of his number showing on one die is $$\frac{1}{6}$$, but since there are three dice, the chances must be $$\frac{3}{6}$$ or $$\frac{1}{2}$$, therefore the game is a fair one. Of course this is the way the operator of the game wants everyone to reason, for it is quite fallacious.
