That's what I thought at first also, because it works for 1 person, 2 people, and 3 people. But if you write out all of the 24 possibilites for 4 people, 9 of them consist of everyone picking someone else's name, instead of 6/24 or 1/4 like it should be if it was 1/n. I wanna figure out the real answer but, I'm kind of feeling too lazy. :lol:
