   Anmerkungen:

   • 7! to arrange bananas. BUTTTTT my eyes can tell the difference between the first and second and third A - so those combos look the same to me. SO we must divide out the repeating numbers. 3 A's and 2 N's. 7! / (3! 2!)
3. Why are letters similar to (car) colors?

1. What is your criteria? Suits (4), Face Value (12), Color (26) etc.

Anmerkungen:
