When playing a game of blackjack, what are the odds that you will be dealt BlackJack on the first deal? Assume you are playing with one opponent and your opponent is the dealer.
Note: 10, jack, queen and king all are worth 10. Aces are worth 11.
You have blackjack when the values of both your cards add up to 21. There is only one deck of cards being dealt out.
How about this?: Black Jack... You against the dealer right? You get dealt first, then the dealer, then you again. You need a figure and an ace to BJ. Two ways of getting it: a) The figure and then the ace = 16/52*((4-(4/51))/50) b)The ace first and then the figure = 4/52*((16-(16/51))/50)... Add... = 4.827% probability or 1 in 20.71775 odds?
