The vig at +1950
If both sides of a two-way market were priced at +1950, the implied probabilities would add up to -90.24% above 100%. That excess is the overround, or vig; as a share of stakes it is a -925.00% margin for the bookmaker. Removing it leaves fair odds of 2.00 decimal ( +100) on each side. Use the devig calculator to do the same for any market.
