2-deck blackjack, also known as double-deck blackjack, is played with two decks and the dealer hits on a soft 17. The rules of 2-deck blackjack may be slightly different from one casino to the next. However, the dealer hits on soft 17. The first two cards are dealt to the player face down. Any cards drawn after the first two are dealt face up.

Learn basic blackjack strategy before beginning to play. Whether you hope to make a fortune counting cards or simply enjoy playing a few rounds of blackjack at the casino table, there are some important pointers to follow.

The Blackjack Basic Strategy Engine above provides a simple way to memorize a variety of different profitable decisions, such as when to split, double, surrender, hit, or stand. A standard basic strategy chart can only provide you with the strategy for one set of rules, such as dealer hits on soft 17, limiting your mastery to just one game. Longer answer: The main reason is whether the Basic Strategy Chart is based off of a dealer Hitting a Soft 17, known as an “H17 game” or Standing on a Soft 17, known as an “S17 game.” Our advice is to learn this chart, then move on to learning card counting and the blackjack deviations associated with the game you will be playing (H17 vs S17). The correct basic strategy for hitting a soft 17 is as follows: For a single-deck game, hit soft 17 when the dealer’s upcard is 7 through ace. For double- and multi-deck games, hit soft 17 when the dealer’s upcard is a 2 or 7 through ace.

In blackjack, the Ace may be valued as either 1 or 11. A hand containing an Ace counted as 11 is called “soft.” If the dealer’s first two cards are an Ace and a 6, his hand is known as soft 17. Any other combination totaling 17 points is hard 17. In some casinos, the blackjack dealer may hit on soft 17. This means that he may draw an additional card.

To find out whether this is an option, take a look at the blackjack table layout. It will say either “Dealer Hits Soft 17” or “Dealer Must Stand on all 17.” The soft 17 rule will increase the house edge by a small amount

I was unable to find it on the internet or this forum. The first question I have is what is the odds of the dealer having a soft 17 in any given hand? Assume six decks. For example, it could be a 6-A but also 3-3 then draw to an ace.
My second question is what is the odds of the dealer busting after reaching/revealing a soft 17?
Any help would be appreciated, I am asking this because I am making a homemade game of a mixture of Blackjack and Baccarat, where players can choose to put money on the player hand or dealer hand. My idea for the dealer's house edge is that if a player bets on the dealer hand and the dealer wins after reaching/revealing a soft 17, it pushes instead of wins. Player's hand house edge is around 0.60% with my rules, and I'm trying to get around the same with the dealer.

It is called scientific notation.
6.486E-07 = 6.486 x 10-7 = 0.0000006486

Thank you Jufo and Gordon. To recap, in my game players can bet that the dealer will win. But if the dealer wins after having a soft 17, the players betting on the dealer will push instead of win. If I combine the 1.7968687% of getting a soft 17 and multiplying it by 78.79% chance of not busting it comes out to 1.42%. Does this mean that the house edge for this game when betting on the dealer would be 0.82% (1.42%-0.60%), 0.60% coming from the approximate house edge)?
My rules are currently 6 deck shoe, 3:2 BJ, DA2, split once, DAS, split ace one card, late surrender. The wizard's calculator puts this at 0.60374%. If no surrender it becomes 0.69205%. That would make the dealer's house edge bet 0.73%. It balances it out more. Now I'm just talking to myself haha.
Anybody please correct if I'm wrong here. Thanks again!

Some combinations are missing there or did you include different orderings in the above, that is 33A includes 3A3 and A33 etc?

1.42% would be the probability of dealer having Soft 17 and not busting, but it doesn't mean that the dealer will win that hand, so it's more complex than that.
And no, you can't calculate the house edge of betting on the dealer like that as it is not directly opposite to the player bet.
So, your target is to have the bet 'dealer wins' as close to zero house edge as possible? And this is assuming that the player side plays optimally because if they don't then bet 'dealer wins' will have an edge. If dealer pushes is the 'dealer wins' bet a push or a loss?
From dealer's side the probabilites are this (Source: https://wizardofodds.com/games/blackjack/appendix/4 ):
Loss 42.42%
Push 8.48%
Win 49.09%
If you want to make this zero house edge by making some wins become pushes the win probability has to be equal to lose probability so you will need to increase the frequency of pushes by 6.67%. The hit soft 17 push rule change will not achieve that.

Yes, 33A included 3A3 and A33 and so on for the other combinations. The sequence doesn't matter in the way I calculated it.
