What Are the Odds of Getting a Blackjack in Spanish 21

[ShipTheCookies]

With a single deck, the odds are 1 in 27.625. So probably a bit higher then that.

Is this right? For single deck Spanish 21, if I calculated correctly, I get:

4/48*12/47*2 = 0.04255
1/0.04255 = 23.5018 or once in about 23.5 hands.

By the way, in playing a lot of online Spanish 21 it seems to me the dealer has an Ace up way more often than in regular blackjack, but has a blackjack way less than regular blackjack. Just seems that way to me.

If 1/12 is way more than 1/13, then yes.

Yeah I miscalculated. Been too busy to fix it.
