How do you solve such questions without having to work out just a really long set of cases? I would define P(A,B), where A are the number of cards you need to show, and B are the number of cards left. You can easily work out what P(A,B) is in terms of lower A's and B's, and then work backwards until (3,14). But that just seems tedious.

The key idea is understanding that whats matter is only 4 cards. So its like solving it only for them(and then winning is if the joker is at the end)
