Poker Hands (Posted on 2004-07-09) Difficulty: 4 of 5
The likelihoods of being dealt various poker hands are widely published (easily found on the internet). A more difficult problem is: what are the likelihoods of being dealt each poker hand, given a 54 card deck (52 card deck + 2 jokers).

The various hands of interest are:
1 pair
2 pair
3 of a kind
full house
4 of a kind
straight flush
5 of a kind

* Jokers can count as any rank card, in any suit.

Just did it in a little spreadsheet, combinatorics.  You have to figure out that ace-high straights come up more often with jokers.  On hands with no jokers, 5-high to ace-high straights occur uniformly; with one, ace-high strights 1.25 times more likely than others; with two, they're twice.
