Interpreting the results of the probability roulette calculator: Here is how you should do the roulette probability formula: The probability is 18/37 and will take the -2 value with 20/37 probability. Here, ” A” is used as the variable for the calculation to represent your winnings in roulette from red that takes the value of 2€. If you bet 2€ on red, but the ball lands on green or black, you will lose your bet (-2). If you bet 1€ on red, and the ball lands on red, you will win it back, and the amount is doubled, so you profit 1€.
