Best ResponseYou've already chosen the best response.0I'd say it is like this: suppose they they leave the elevator one by one. For the first person, it doesn't matter where he or she leaves. For the second one, there is a 1/15 chance that he/she also leaves. The third one: also 1/15. To have them both leave at the same story: 1/15 * 1/15 = 1/225.
