1. 7 friends are ordering themselves, but Chloe must be in the middle. How many ways can this happen?

2. You have 12 formulas to memorize how many ways can you memorize them?

3. A store sells 5 different shirts, 6 different pants, 3 different shoes, and 9 different socks. You are making an outfit with one of each article of clothing. How many outfits can you make?

Note: There is a specific answer (a number) of how many possible outcomes can occur for all of them using formulas for permutations. I have limited time on this (please don't include large explanations). Please answer all the questions if you can, if not, definitely answer #1. Thank you!
