In roulette, there are 36 numbers that can be chosen from. These are divided into black and red. Black numbers are worth 0 points, while red numbers are worth 1 point.
This means that, on average, a bet on roulette will give you a 1 in 36 (0.16%) chance of winning.
As with all casino games, it is important to take into account the house edge when making your roulette bets. The house edge in roulette can vary depending on the particular casino, but it is typically around 0.
5%. This means that for every $100 you bet on roulette, the casino will earn $5 back in winnings.
