The answer depends on the design of the spinner: how many sides and what numbers on them.
If the probability of an event will occur is p, then the probability that it will occur in n trials is pn.(That's p raised to the n power). So if you bet on 12 numbers, then (38-12=26) numbers are empty. The probability of the ball landing on one of these empty numbers is 26/38. So (26/38)^11 = 0.01538, which is about 1.538 % or a 1 in 65 chance.
If a five color spinner with equal sections of red blue green yellow and orange is spun six times, the probability of getting no reds in all six spins is 26.2%. The probability of no red on one spin is 4 out of 5, or 0.8 The probability of no red in six spins is 0.86.
The answer depends on the shape of the spinner and the numbers on it.
The chances of one of these numbers NOT appearing on one spin are 29 out of 37 ie 78.4%, so for 40 spins it is (29/37)^40 which is a remote 0.006%!

The probability is 0.0198. The probability of that happening twice is 0.000393 Is this the odds of it happening twice with the same number?
Its name says it all. It simply spins and stops at your command.
The odds of hitting the same number twice in a row on a single-zero roulette wheel (European) is 1 in 3,600 (37 possible numbers). On a double-zero roulette wheel (American), the odds are 1 in 3,704 (38 possible numbers).
If you mean by the players, no. If you mean by the dealers, yes.
If a five color spinner with equal sections of red blue green yellow and orange is spun six times, the probability of getting no reds in all six spins is 26.2%. The probability of no red on one spin is 4 out of 5, or 0.8 The probability of no red in six spins is 0.86.
That woul mean that the ball landed in one of the remaining 29 slots for 41 and 42 spins. Therefore the answer is 29/37^41 and 29/37^42
The answer depends on the shape of the spinner and the numbers on it.
Roulette is a game of chance. It utilizes a wheel that has different compartments (red or black) with different numbers. The wheel is spun and a small metal ball rolls around the wheel until it comes to a stop in a compartment. Players can bet on what color or number the compartment will be.
