You’re given a frequent buyer card for your local coffee shop. Each time you buy a cup
of coffee you get a stamp on your card. When the card is filled, you get a free cup of
coffee. Here are two different scenarios:
Card A: The card has 10 boxes for the stamps, and when you get the card, all
the boxes are blank.
Card B: The card has 12 boxes for the stamps, and when you get the card the
first two boxes are already stamped.
