 Dec 15 awarded Caucus May 14 awarded Caucus Jul 5 comment Question about basic strategy in Blackjack Well, if the player has 10+5 and the dealer has a 6 and an ace, I think the dealer could stand. Jan 12 awarded Yearling Jan 10 awarded Announcer Sep 18 answered Calculating interquartile range Jan 18 comment 1D random walk-probability to go back to origin I am not sure. I must miss something, but with your computation: $P_{1}=\frac{\frac{1}{3}}{\frac{2}{3}}=0.5$. But I think it should be $\frac{1}{3}\cdot\frac{2}{3}+\frac{2}{3}\cdot\frac{1}{3}=0.4444$. What is the problem with my computation? Jan 18 comment 1D random walk-probability to go back to origin @Yakov: that sounds tough :) I am trying to work out a solution, but see no easy way. Till then, please see my edited answer above, that may help finding the way.

The number of decks in play only affects the probability of getting a card what have been seen before (what I left out of my example, as I stated), which is not a very big deal in blackjack - not like in poker. Also, 4+ decks in play serves the purpose of making more difficult counting the cards (so: cheat), and also the ease: as the dealer do not have to shuffle the deck every turn. And of course also increases the house edge. In your example, the prob. is so high, that more decks do not make tangible difference.

Jan 13 comment skew normal distribution By this way you will get a distribution with a skewness atound 0.850965 as computed at your corresponding question at stackoverflow (look for the link above).
