| Implied | Fair, multiplicative | Fair, power | |
|---|---|---|---|
| Outcome 1 | 52.63% | 50.00% · 2.00 | 50.00% · 2.00 |
| Outcome 2 | 52.63% | 50.00% · 2.00 | 50.00% · 2.00 |
How it works
The multiplicative method divides each implied probability by the sum of all of them, so every outcome loses the same share. The power method raises each implied probability to one common exponent until they sum to 100 percent, which takes more margin off longshots. Fair odds are 1 divided by the fair probability.
