The roulette desk usually imposes minimum and maximum bets. Players can continue to place bets as the ball spins around the wheel until the dealer announces "no more bets" or "rien ne va plus".
The payout ratio for a bet depends on its probability. A probability of 100 percent means the safe arrival of an event, and a value of 0, the safe lack of an event. In roulette the payout ratio increases proportionally with decreasing probability. In other words: the the lower the probability, the higher the payout.
If you want to know the percentage probability of a bet type in roulette you simply need to calculate this:
Probability of 1 Number is: 1: 37 * 100 = 2.7% in european and 1: 38 * 100 = 2.6% in american roulette.
If 2 Numbers are played the winning probability is: 2 * 2.7% = 5.4% in european and 2 * 2.6% in american roulette.
