I would like to know how many possible combinations there are to get 3 cards to a straight in a 5 card poker hand WITHOUT having 3 of a kind or better.
(Standard 52 card deck, no wilds)
I'd also like to ask the same question but with combos of having 4 cards to a straight. I believe all I need to do is subtract 13 from 101808 (from 4 card poker) but I'm not sure. Please help! Thank you
1. Are you trying to make the best three card poker hand from a 5 card hand? Do you want to know how often you will be able to make a 3-card straight without also having a 3 card flush, 3-of-a-kind, or a three-card straight flush?
2. In the first part of your question, if your 5 card hand can make a 4-card straight does that qualify as a 3-card straight - or must it be 3 -and no more than 3 -consecutive cards in rank?

Would a hand like 2s, 3h, 5d, Ks, Qc count as "3 to a straight"? You don't mention that they have to be in consecutive order (2,3,4; 6,7,8).
1) the best three card hand doesn't matter nor does a three card flush/straight flush.
2) it must be 3 and no more than 3 consecutive cards in rank.
If I'm dealt 5 cards from a standard deck, what is the probability that I'll have only a 3 card straight? So, no 3 of a kind or better. Making a pair or having two pair along with the 3 card straight is fine. Ex. Ace, 2, 3, 2, 3
As for the 2nd part of my question, I think it can be answered by taking the math from the game 4 card poker on how many straight combinations there are (101808) minus the 5 card straight combinations.
And then there's the other thing:
Goons ???Quote: JACKHopefully the Wizard or one of his goons can help.
More Detail
I calculate that the AKQ and 32A 'straights' are the most frequent, at 0.024157 each (with the proviso of no 3-of-a-kind.) (62,784 combinations each.)
I calculate that the other 10 3-card straights, from KQJ to 432, each have a frequency of 0.019971. (51,904 combinations each.)
And, btw, I am not "one of the Wizard's goons."

Well, we don't know Jack. And if you keep up the name-calling, we never will. Personal insults not tolerated here. Warning. Remains to be seen if you're a Biff - troll or just kind of humorously aggressive.
If you have the time, could you show me how you got those numbers? If not, no big deal. Thanks again!
1) AKQ, A23 (2 straights -gut shots to make a 4-card straight)
2) KQJ ... 432 (10 straights -open-ended to make a 4-card straight)
For group 1, let's do AKQ
AKQ = (1 combo) * 3^4. For the other two cards in the hand, they are defined to not be a Jack (which would turn it into a four card straight) so that is combin(45,2). The 45 is 52 - 3(cards in your hand) - 4 (Jacks). The last two cards also cannot be AA or KK or QQ (because you said no trips), and there are three ways left to make each of those three pairs. So
AKQ = 1*(3^4)*(combin(45,2)-3*3) =62,784.
With 32A, the remaining 2 cards cannot be a 4, so we use the same formula for another 62,784 combinations, so group 1 is 125,568 combinations
Group 2. These straights are the same formula except the last two cards cannot be from either of the two ranks that surround the straight, i.e., for T98, the last two cards cannot be a J or 7, so the formula for each of these straights is 1*(3^4)*(combin(41,2)-3*3), multiply that by 9 (for 9 straights) =519,040 combinations.
*********************
For the four card straights, its the same deal -divide them up into two groups,
Group 1: AKQJ and 432A
Group 2: The other 9 straights: KQJT ... 5432
And there are no 3-of-a-kinds to worry about so the total number of combinations is:
2*(4^4)*44+9*(4^4)*40=114,688.
Your original approach to the four card straight calculation was not right, probably because the number of combinations you were starting with excluded all 4-card (or 5-card) flushes, and you had specified that you did not want flushes and straight flushes to be excluded from the number of combinations.

All good, Jack, and welcome to the board.
