Question

Charlene has nine different necklaces, and she wears four at a time. How many different ways can Charlene wear four necklaces?

Answer 1

4! (4*4*4*4) = 24
24 ways

Answer 2

I don't know, but I think it is 9 times 8 times 7 times 6 which is 72 times 42 which is 3,024. I am probably wrong, but yeah.
