I appreciate the responses so much, having majored in Mathemagic, that I will pose another question.
How many combinations of the 12 cards shown can be made to form a Baker's Dozen?
Answer correctly and you can purchase all 12, or is it 13, for
$40 shipped.
Please answer only if you intend to purchase.
