What Is the Expected Value of Roulette?

Roulette is a casino game with a long and rich history. The game is thought to have originated in France in the 18th century, and has since become one of the most popular games in casinos around the world. Roulette is played on a wheel with 37 or 38 numbered slots, depending on the type of roulette you are playing.

Players place bets on where they think the ball will land after the wheel is spun. There are many different types of bets that can be placed in roulette, and the odds of each type of bet vary depending on what you are betting on.

The expected value of roulette is the amount of money that you would expect to win or lose if you were to play the game for an infinite amount of time. The expected value depends on the type of bet that you are making.

For example, if you are betting on a single number, your expected value would be negative because the odds of winning are less than 50%. However, if you are betting on a group of numbers, your expected value would be positive because your chances of winning are greater than 50%.

In general, the expected value of roulette is negative because the house always has an edge over the player. However, there are some bets that have a positive expected value, such as betting on a group of numbers.

If you want to win money in roulette, it is important to know which bets have a positive expected value and to only make those bets.
