The probability of seeing the same color appear on successive spins just over halves from one spin to the next. Number of SpinsĮxample: The probability of the same color showing up 6 times in a row on an American roulette wheel is 1.13%. The 0 appearing at least once over 10 spins.Ī graph to show the probability of seeing the same color of red/black on an American roulette table (compared to the odds on a European table). I stopped the graph at 6 trials/spins, as that was enough to highlight the trend and produce a prettier probability graph. Number of SpinsĮxample: The probability of the same color showing up 4 times in a row is 5.60%.Īs the graph shows, the probability of seeing the same color on consecutive spins of the roulette wheel more than halves (well, the ratio probability doubles) from one spin to the next.

A graph to show the probability of seeing the same color of red/black (or any evens bet result for that matter) over multiple spins.
