1. The object is for players to observe licence plates on motor vehicles in a parking lot and note the last two numbers on each plate. They continue to observe licence plates until a match is found or they note 20 licence plates. This completes a round of play. Before doing so, each player makes a prediction about whether or not there will be a match.
2. One player acts as the bank and distributes five chips of the appropriate colour to each player.
• Players who predict there will be a match get chips of one colour.
• Players who predict there will not be a match get chips of another colour.
Players play against the bank.
3. The winners in a round receive a chip. The losers must pay a chip.
4. Play at least six rounds.
5. Determine which prediction is more likely to win.
