P(Black)
Expected return on a $10.00 bet
Probability of Black
| Probability of Black = | Total Black |
| Total Spaces |
| Probability of Black = | 18 |
| 38 |

Calculate Success % of Black
Success % = Probability of Black x 100%
| Success % = | 9 x 100% |

Success % = 47.37%
Calculate the Expected Return
Expected Return = Bet * (Success % - (1 - Success %))
Expected Return = $10.00 * (0.47368421052632 - (1 - 0.47368421052632))
Expected Return = $10.00 * (0.47368421052632 - 0.52631578947368)
Expected Return = $10.00 * -0.052631578947369
