P(4 Numbers)
Expected return on a $10.00 bet
Probability of 4 Numbers
| Probability of 4 Numbers = | Total 4 Numbers |
| Total Spaces |
| Probability of 4 Numbers = | 4 |

Success % = 10.53%
Calculate the Expected Return
Expected Return = Bet * (Success % - (1 - Success %))
Expected Return = $10.00 * (0.10526315789474 - (1 - 0.10526315789474))
