With a starting hand of three deuces, what are your odds of getting a hand better than four of a kind.
It would be a straight flush, a wild royal or five of a kind, but I'm not sure how to figure the chances of each.
Any help would be appreciated.
The difference between fiction and reality is that fiction is supposed to make sense.

Wizardofodds.com has a hand analyzer in the video poker section. Choose a deuces game and hold three deuces and two random cards. It will show the probability of each potential hand.
At my age, a "Life In Prison" sentence is not much of a deterrent.

Also 4 deuces, fwiw, among those improved hands the OP listed.
If the House lost every hand, they wouldn't deal the game.

It depends on the discards. For example, tossing unsuited Ace-Ten can make fewer Wild Royals than tossing 3-8.

Looking at all 3-deuce starting hands (even those which are already better than 4-of-a-kind, except 4 deuces), the probabilities of improving range from 24.05% to 24.7%.

The discards most likely to improve are 33 and KK. (Not necessarily the best EV, just most likely to improve beyond 4-of-a-kind.)
The discards least likely to improve are unsuited 78, 79, 7T, 89, 8T, and 9T.

Interesting observations:
- 3 deuces is more likely to improve to 4 deuces than to a Wild Royal, no matter the discards
- 5 of a kind is more likely when the starting hand was 5 of a kind

Thank you, but I guess my question is more complicated than I thought.
Allow me to rephrase it.
Assume a player uses proper strategy and doesn't break up either a royal flush or five of a kind. That eliminates a number of the possibilities listed.
Drawing on three dueces, what are the chances of improving it beyond four of a kind?
Still in the 20-25 percent range? An exact percentage isn't necessary.
The difference between fiction and reality is that fiction is supposed to make sense.

Excellent response!

This website along with inquisitive gamblers everywhere are very fortunate that you are able and willing to calculate and publish stuff like this.

Yes, just skip the hands that don't apply.
Including them, the range was 24.05% to 24.7%.
Excluding them, the range is 24.05% to 24.6%.
So a little worse than 1 in 4.

I'd imagine one mistake every seven years or so is fairly acceptable. Unless we are talking marriages.

I've made plenty of mistakes. Usually the quicker I respond to something, the more likely it is to be in error.

The figures in my table on page 1 came from WinPoker, which is known to contain an obscure bug, but I think it was accurate here.
