What are the odds

Yes, I did. Out of 2598960 possible 5 card poker hands in a deck, there are 32 non-royal straight flush combinations for odds of 0.00001385 (1 in 72,000) and 4 possible royal flush combinations at odds of 0.00000153908 (1 in 650,000). So even a Royal flush is more common than one in a million

The player can get also a straight flush with A,2,3,4,5 suited.

So 8 possible combinations for the player to get.

0.00001385 or roughly 1 in 72,000
I think you are basing your calculations on the possibility of getting a 5 card straight flush in a game where you get 5 cards regardless of their value. You can't get a straight flush in BJ if the cards you are dealt  are 7,8,9,10,J because the dealer would not have given you any cards after dealing you 7,8,9 as your total is 24 and, as that is over 21 you lose, the dealer scoops your cards and your money.

This is true, my odds are based off straight 5 card stud poker, I am certainly not a strong enough mathematician to calculate the odds based on blackjack rules. Essentially ignore my post. Thanks for the reply.

EDIT: Also apologies to Korvtraktor, I misread your post which said essentially the same thing

Neither am I. 

The odds of getting either of the 2 possible straight flushes would be half the odds of getting a royal flush as it is twice as likely..

royal flush combinations at odds of 0.00000153908 (1 in 650,000).
So it must be around 1 in 325 000

I say this with absolute uncertainty.

This seems correct if the calculations are based on one pack of cards. I'm not much of a BJ player but does LV use more than one pack to avoid counting? This would throw the odds off a bit, wouldn't it?

 
Hmmmm,

I didn't think about that.

They either use 6 or 8 decks.

Well I have no idea how that affects things. I have a "feeling" it would be in the same ballpark.

I hope someone who can work this kind of thing out chimes in.

Sure as hell isn't me; got a headache just thinking about it.

On second thought as you increase the decks, the amount of potential 5 card combinations increases but so do the amount of potential straight flush combinations, at the same rate. I don't think it would affect the odds

 
Hey! I've done some maths and tried scribbling it down but honsestly most of it is in my head. I've calculated it from trying to get it and not caring about strategy and if you bust on the last card it's still a straight flush. It came down to 1÷397440 but since this is not an optimal strategy the odds are way lower in reality. Hope I got this right :) (Also I realize now I missed the odds of not being able to hit sknce you're already at 21 example A,6,4 so it's even lower than what I calculated)
