The vig at -202

If both sides of a two-way market were priced at -202, the implied probabilities would add up to 33.77% above 100%. That excess is the overround, or vig; as a share of stakes it is a 25.25% margin for the bookmaker. Removing it leaves fair odds of 2.00 decimal ( +100) on each side.
