Probability and Odds in Roulette

The Concept of Probability in Roulette

The concept of probability in roulette is complex, to say the least. Depending on if you’re using tablets and wheels for European roulette, American roulette, and French roulette, there are different probabilities right away. Namely, the house has an edge in American roulette because they get both 0 and 00 on the wheel, reducing the chances of you winning on a single number from 36 to 1 to 37 to 1.

That being said, the way to understand probability in the context of roulette requires looking at the probability roulette spins that turn out in your favor vs. those that are not in your favor.

Basically, if you bet on a single number, you have a European wheel, you have 1 way to win and 36 ways to lose. The formula for this is probability of winning is equal to the Ways to Win / (Ways to Win + Ways to Lose) So, your probability of a win would be 1/(1+36) or 1/37 or 2.70%.

Roulette Strategies

Can You Use Probability Theory to Develop a Betting Strategy?

One thing that people often wonder is whether or not they can use probability theory to develop a betting strategy. The popular roulette odds strategies involve people making spreadsheets, watching for when to follow the wheel and when to bet against it and more. The fact of the matter is that you can develop a betting strategy, but it will not influence the odds. You can mitigate as much risk as possible and come away with small amounts of real money, but you can still lose.

How to Increase Player’s Chances of Winning

Increasing your chances of winning is nearly impossible to do. The best thing that you can do is know the rules of the game. You have to understand the bets that will give you winnings and which ones will not help you win. Only by doing this can you successfully increase your chances. Otherwise, you cannot interfere in the game at all.

It’s Still About Luck!

Luck is the only thing that you can count on when it comes time to bet on roulette. You either have good luck or you don’t. The ball can weirdly skim the wheel and land on your number, or the croupier could end up falling into a streak where they toss the ball and it only lands on black for a few turns. It’s all luck in the end!
