  1. I need clarification on #7 from the assignment… Does the order of the seating matter or is it just asking how many ways to divide the group? Also, do all of the couples have to be directly beside each other or is it enough that they’re in the same area?

    1. Good questions.

      Order does matter, so if two people were to switch seats while staying in the same area it would count as another arrangement.

      Couples must sit in seats next to each other (adjacent seats).
