Any basic statistics book should have a standard normal table which will give the Z statistic of 0. For how to solve the problem yourself, see my MathProblems. Here is how I did it. I hope this answers your question. 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 not get a third eight on either hand.

Determine the probability that the player will resplit to 3 hands. Blackjack is not entirely a game of independent trials like roulette, but the deck is not predisposed to run in streaks. This is not even a marginal play. Multiply dot product from step 7 by probability in step 5. 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. Thanks for your kind words. In general the variation in the mean is inversely proportional to the square root of the number of hands you play. For the non-card counter it may be assumed that the odds are the same in each new round. For each rank determine the probability of that rank, given that the probability of another 8 is zero. From my blackjack appendix 7 we see that each 9 removed from a single deck game increases the house edge by 0. There is no sound bite answer to explain why you should hit. Your question however could be rephrased as, "what is the value of the ace, given that the other card is not a ten. Resplitting up to four hands is allowed. Is it that when I sit down at the table, 1 out of my next playing sessions I can expect to have an 8 hand losing streak? I have a very ugly subroutine full of long formulas I determine using probability trees.{/INSERTKEYS}{/PARAGRAPH} Take the dot product of the probability and expected value over each rank. So the probability of winning six in a row is 0. Repeat step 3 but multiply by 3 instead of 2. However if you were going to cheat it would be much better to remove an ace, which increases the house edge by 0. I recently replaced my blackjack appendix 4 with some information about the standard deviation which may help. Multiply dot product from step 11 by probability in step 9. 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? 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. It took me years to get the splitting pairs correct myself. It is more a matter of degree, the more you play the more your results will approach the house edge. There are cards remaining in the two decks and 32 are tens. If I'm playing for fun then I leave the table when I'm not having fun any longer. Add values from steps 4, 8, and The hardest part of all this is step 3. The fewer the decks and the greater the number of cards the more this is true. When the dealer stands on a soft 17, the dealer will bust about When the dealer hits on a soft 17, the dealer will bust about According to my blackjack appendix 4 , the 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.

If there were a shuffle between hands the probability would increase substantially. 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.

Determine the probability that the player will resplit to 4 hands. All of this assumes flat betting, otherwise the math really gets messy. So, the best card for the player is the ace and the best for the dealer is the 5. You ask a good question for which there is no firm answer. In that case, the probability of a win, given a resolved bet, is The probability of winning n hands is a row is 0. I would have to do a computer simulation to consider all the other combinations. 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. Besides every once in awhile throwing down a bigger bet just adds to the excitement and for some reason it seems logical that if you have lost a string of hands you are "due" for a win. Multiply this dot product by the probability from step 2. Thanks for the kind words.
