Question by Sarr: Interesting math problem – gambling statistics?
You walk into a casino with 00 in your pocket. Your game strategy is to maximize the probability of a win. A win is defined
as an event in which you leave the casino with more money than you came in with. Your tactics is to always bet on ”black” in roulette, which has 1/2 probability of success. Once the wheel is spun, and the ball falls on ”black”, you get back twice the money you bet; otherwise you get back zero. Your tactics is ”bet doubling”: you double your previous bet after each loss. The minimum allowed bet is , maximum ,000. You have made up your mind to leave immediately in case of a win (according to the definition above). You also must leave if it becomes clear you
can not win.
Question 1: What is the probability of loss (”loss” = ”not win”) in the above strategy?
Question 2: If such loss occurs, how much money will still be left in your pocket as you leave?

Okay, the pattern follows 2^(n-1), where n = bet number

n – bet amount (assuming all losses)
1 1
2 2
3 4
4 8
5 16
6 32
7 64
8 128
9 256
10 512

When you sum up your bets, you can only get to the 9th one, totaling 511 dollar loss, so you have 489 left and can’t make your next bet.

So what is the probability of a loss?

Thanks for your help.

The probability of loss is (1/2)^9, or 1/256.
If this occurs, you will be left with 9.

This strategy of bet doubling is known as the Martingale and has been widely proven unsuccessful due to betting limits.

Technically, in the context of roulette your statement that the probability of getting black is 1/2 is not true. The 00 makes a big difference, and swings the game in favour of the house. This 00 is why there is no such thing as a Roulette “system”, a strategy that will guarantee gains.

Baccarat is my favorite casino game. You have a seat at the table and then decide you you bet on banker, player, or tie. It is said that baccarat goes in a pattern, and sometimes it does sometime it doesnt.
So after you decide on what you are going to bid on the dealer deals the cards. the winner is the one closes to nine! there are natural 8 and 9. You would have to sit and watch to understand it. once you do you will be addicted
