Suppose there are 3 roommates in a deadly shootout situation. We’ll say they’re using water guns (the new and improved Super Soaker 9999) and the worst that can happen is that they get drenched, in which case they’re “dead”. Roommate #1 gets to shoot first, but only hits his target 33% of the time. Roommate #2 gets to shoot second and hits his target 50% of the time. And Roommate #3 gets to shoot last and never misses. This continues until only one person is left standing. Assuming there are no hard feelings and there are no shots after one is “dead”, what should Roommate #1 do with his first shot so that he has his best chance of escaping with dry clothes? I’ll give you the answer next Monday, but feel free to email me earlier if you think you know.
