The person at the back of the line is chatting with someone who is still shopping and will stay at the back of the line. How many different ways can the other shoppers in line be​ ordered?

Answer 1

362880

You have to subtract the two people who are already doing something in line so you would do 11-2 which equals 9. Then you would do 9 mPr 9 which gives you an answer of 362,880.
