Odds are everywhere you look. Seriously. Odds are in a casino, your workplace, your day-to-day live and habits, your marriage and where in the world you live.

Probability of Blackjack. Probability 1 4.827% 2 4.780% 3 4.764% 4 4.757% 5 4.752% 6. Another way of looking at it is to turn it upside-down to find the odds: 663 ÷ 32 is (aptly) about 21 – so if you played 21 games you'd only expect to get one blackjack. Something to think about How many games would you have to play so that the probability of getting at least one blackjack was greater than 0.5?

Don’t believe me? Take a look for yourself:

  • Odds of having twins (21st century) – 3 in 100 or 3%
  • Odds of getting a divorce – 40 to 50%
  • Odds of being stuck by lightning – 1 in 5,000 or 1 in 700,000 in any given year
  • Odds of being audited by the IRS – .4% if you make less than $200,000 / year
  • Odds of being dealt a blackjack – About 4.83%

Odds are just the likelihood that something will happen. As a blackjack player you deal with this all the time.

Lets look at a couple real examples to show you what I mean.

Here are the odds of you busting your hand, depending on what you were dealt:

  • 21 – 100%
  • 20 – 92%
  • 19 – 85%
  • 18 – 77%
  • 17 – 69%
  • 16 – 62%
  • 15 – 58%
  • 14 – 56%
  • 13 – 39%
  • 12 – 31%
  • <11 – 0%

Odds of Being Dealt Specific Hands

Here are the probabilities for being dealt a specific hand:

  • Blackjack – 4.8%
  • Standing Hand (17-20) – 30%
  • Decision Hand – (1-16) – 38.7%
  • No Bust – 26.5%

Here are the odds for the final hands that the dealer will make:

  • Natural 21 – 4.82%
  • 21 (3+ cards) – 7.36%
  • 20 – 17.58%
  • 19 – 13.48%
  • 18 – 13.81%
  • 17 – 14.58%
  • 16 – 28.36%

Dealer vs. Player Odds

Finally, here are the odds of the dealer busting based on their up card:

What Are The Odds Of Getting Blackjack
  • 2 – 35.30%
  • 3 – 37.56%
  • 4 – 40.28%
  • 5 – 42.89%
  • 6 – 42.08%
  • 7 – 25.99%
  • 8 – 23.86%
  • 9 – 23.34%
  • J,Q,K – 21.43%
  • A – 11.65%

Of these examples, this is the most useful. Notice what hands the dealer is most likely to bust with. The dealer will most often bust with 4, 5 or 6, followed by 2 and 3.

The odds above are static. There’s nothing you can do to change them. However, you can find ways to improve your odds so that you lose fewer hands and less money. And the less money you lose, the more you can keep to play more blackjack.

Here’s what you can do to improve your odds in blackjack:

  • Use basic blackjack strategy. Without basic strategy you’re playing at an 8% disadvantage. With strategy, however, the odds increase significantly. You’ll be playing at only .5 to 1.5% disadvantage.
  • Find the best games. The rules make all the difference. For example, if you play a 6:5 blackjack game you’re adding a 1.39% disadvantage. If the dealer hits soft 17 that’s another .18%. However, it’s possible to find games where the player is paid 3:2 for blackjacks and the dealer stands on soft 17. So find those games. Also be careful about which blackjack variation you play. The best games to play are blackjack, Spanish 21, Vegas Strip BJ and Blackjack Switch.
  • Avoid side bets. Side bets look exciting, because for a nominal amount you could possibly win a huge jackpot — worth hundreds or even thousands of dollars. The problem is that the odds against winning can be anywhere from 2-40%.
  • Avoid wives tales. There are a lot of bad strategies like never busting (never hit a 12+), mimicking the dealer and assume that the dealer has a 10 in the whole (with ace up). The problem with using any of these strategies is that they increase the house edge from 3 to 10 percent.

You can do other things, too, like count cards or read books (usually a mix of basic strategy, card counting and general how-to’s for casino blackjack). However, you’ll improve your odds at winning at blackjack just by following my suggestions above.

Understanding the Long Run – Sample Size and Variance

What are the odds of getting a blackjack

I wanted to finish up this article with a brief explanation of odds, and how they work over the long run. You see, I think a lot of people will see the numbers above and get confused when they don’t match their own stats. In other words, someone might go to the casino play 500 hands of blackjack, and wonder why they didn’t get 24 natural blackjacks, or the other way around, why they got 42.

The thing is, odds and statistics are all about the long run. Long run usually meaning sample size, or the total number of hands (or games) played.

What Are The Odds Of Getting Blackjack

What that means is that over a significant sample size, hundreds of thousands or even millions of hands, the number of times you’ll receive a blackjack is about 4.82%. The more hands you play the truer this will become.

The reason why odds don’t match up in smaller sessions, say over 500 hands, is because of variance. There’s a technical term and definition for variance, but I’ll just give you my version; variance is the ups and downs you experience on your way to the long term (expected) results.

Mike Caro, a poker player and author, puts it this way:

A measure of the spread of statistical distribution about its mean or centre.

That means in a short time frame, it’s possible to experience more drastic odds. You might win or lose more than you’re supposed to. It also explains why people can go into a casino, not use basic strategy and win 3x as much as what they walked in with. The cards ran in their favor — they experienced a positive streak of variance.

So that’s the gist of it. So the next time you walk into the casino and have a wild swing one way or another, you know that that’s not normal, and that in the long run you’ll be closer to break-even so long as you stick to basic strategy — the plan with the best odds.

I hit my favorite riverboat this weekend, and after a while was up a good bit so decided to play one last shoe. Playing heads-up against the dealer, my first three hands were blackjacks. I pushed on the fourth hand, and decided that was as good a time as any to color up.
Were I not so numerically challenged, I suspect I could find a table from the Wizard that would let me figure the odds of this happening. Failing that, what are the odds of hitting three blackjacks in a row in double deck, H17?
Also, is there any data out there on the odds of getting on a streak of winning hands? Odds to win two in a row, three, four, etc.?

The probability for hitting 3 naturals in a row in 2-deck game is 0.01091938530493739931408503954244% or once every 9158.024669647216796875 attempts.

I have not seen any streak tables by the Wizard. Qfit has some.
The other poster reply assumes the probability of a Blackjack remains constant and we know it does not.
But that does show it to be much more difficult than say 1 in 100 or even 1 in 1000.Blackjack
The more cards the dealer draws without an Ace or a 10 the higher the probability of you getting 3 in a row naturals.
I say between 1 in 11,000 to 1 in 12,000 attempts would be a closer guess.
This could be simulated

So I can't count on this happening every time I sit at the table, huh ...
Thanks for the information. I knew it was a rare event, but was curious to know how rare.

The short answer is this:

What Are The Odds Of Getting Blackjack Poker

Shit happens.
The long answer is this:
The odds of it happening, on the very next three hands, are mighty low.
The odds of it happening on your next visit are low. But not nearly as low as for the specific next three hands. How low depends on how long you sit at the table.
The odds of it happening at some point within your gambling career are mighty high. I dare say that it's likely to happen several times if you're a fairly regular player...
