The probability of a given outcome happening is quite simple to calculate. All you have to do is divide the number of desired outcomes by the number of all.

This is quite a complex problem (since it's not just one question, you're devising a strategy for a whole rational game). I'll give you an idea of how I would go.

If there were a shuffle between hands the probability would increase substantially. I recently replaced my blackjack appendix 4 with some information about the standard deviation which may help. This is not even a marginal play. According to my blackjack appendix 9H the expected return of standing is So my hitting you will save 6. I have no problem with increasing your bet when you get a lucky feeling. There are 24 sevens in the shoe. All of this assumes flat betting, otherwise the math really gets messy. Your question however could be rephrased as, "what is the value of the ace, given that the other card is not a ten. I would have to do a computer simulation to consider all the other combinations. Determine the probability that the player will resplit to 3 hands. In that case, the probability of a win, given a resolved bet, is The probability of winning n hands is a row is 0. So, the best card for the player is the ace and the best for the dealer is the 5. Any basic statistics book should have a standard normal table which will give the Z statistic of 0. It depends on the number of decks. You ask a good question for which there is no firm answer. It may also be the result of progressive betting or mistakes in strategy. I know, I know, its some sort of divine intervention betting system I am talking about and no betting system affects the house edge. Thanks for your kind words. The probability of this is 1 in 5,,, For the probability for any number of throws from 1 to , please see my craps survival tables. Multiply this dot product by the probability from step 2. Steve from Phoenix, AZ. It depends whether there is a shuffle between the blackjacks. These expected values consider all the numerous ways the hand can play out. So standing is the marginally better play. Putting aside some minor effects of deck composition, the dealer who pulled a 5 to a 16 the last five times in a row would be just as likely to do it the next time as the dealer who had been busting on 16 for several hours. If I'm playing for fun then I leave the table when I'm not having fun any longer. From my blackjack appendix 7 we see that each 9 removed from a single deck game increases the house edge by 0. Add values from steps 4, 8, and The hardest part of all this is step 3. Determine the probability that the player will not get a third eight on either hand. Multiply dot product from step 11 by probability in step 9. For how to solve the problem yourself, see my MathProblems. Or does it mean that on any given loss it is a 1 in chance that it was the first of 8 losses coming my way? The standard deviation of one hand is 1. Probability of Blackjack Decks Probability 1 4. That column seemed to put the mathematics to that "feeling" a player can get. Take the dot product of the probability and expected value over each rank. Expected Values for 3-card 16 Vs.

This is a typical question one might encounter in an introductory statistics class. Go through all ranks, except 8, subtract that card from the deck, play out a hand with that card and an 8, determine the expected value, and multiply by 2.

Here is the exact answer for various numbers of decks. If the probability of a blackjack is p then the probability of not getting any blackjacks in 10 hands is 1- 1-p For example in a six deck game the answer would be 1- 0.

When the dealer stands on a soft 17, the dealer will bust about Blackjack probability equation the dealer hits on a soft 17, the dealer will bust about According blackjack probability equation my blackjack appendix 4the probability of a net win is However, if we skip ties, the probability is So, the probability of a four wins in a row is 0.

Https://apocalipsys.ru/blackjack/hands-to-fold-in-texas-hold-39-em.html it that when Blackjack probability equation sit down at the table, 1 out of my next playing sessions I can expect to have an 8 blackjack probability equation losing streak?

Following this rule will result in an extra unit once every hands. It is more a matter of degree, the more you play the more your results will approach the house edge. There is no sound bite answer to explain why you should hit. I have a very ugly subroutine full of long formulas I determine using probability trees.

In general the variation in the mean is inversely proportional to the square root of the number of hands you play. Cindy of Gambling Tools was very helpful. Unless you are counting cards you have the free will to bet as much as you want. Multiply dot product from step 7 by probability in step 5. To test the most likely case to favor hitting, 8 decks and only 3 cards, I ran every possible situation through my combinatorial program. According to my blackjack appendix 4 , the probability of an overall win in blackjack is I'm going to assume you wish to ignore ties for purposes of the streak. Repeat step 3 but multiply by 3 instead of 2. The fewer the decks and the greater the number of cards the more this is true. If you were to add a card as the dealer you should add a 5, which increases the house edge by 0. Streaks, such as the dealer drawing a 5 to a 16, are inevitable but not predictable. Because the sum of a large number of random variables always will approach a bell curve we can use the central limit theorem to get at the answer. Determine the probability that the player will resplit to 4 hands. What you have experienced is likely the result of some very bad losing streaks. What is important is that you play your cards right. So the probability of winning six in a row is 0. I hope this answers your question. However if you were going to cheat it would be much better to remove an ace, which increases the house edge by 0.

For the non-card counter it may be assumed that the odds are the same in each new round. You are forgetting that there are two possible orders, either the ace or the ten can be first. For each rank determine the probability of that rank, given that the probability of another 8 is zero. The following table displays the results. The best play for a billion hands is the best play for one hand. If you want to deviate from the basic strategy here are some borderline plays: 12 against 3, 12 against 4, 13 against 2, 16 against Deviating on these hands will cost you much less.

Repeat step 3 but multiply by 4 instead of 2, and this time consider getting an 8 as a third card, corresponding to the situation where the player is forced to stop resplitting. Let n be the number of decks.
