According to my blackjack appendix 9H the expected return of standing is So my hitting you will save 6. I hope this answers your question. I have a very ugly subroutine full of long formulas I determine using probability trees.{/INSERTKEYS}{/PARAGRAPH} That column seemed to put the mathematics to that "feeling" a player can get. 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. Thanks for the kind words. You ask a good question for which there is no firm answer. 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? Following this rule will result in an extra unit once every hands. Determine the probability that the player will not get a third eight on either hand.
