Converting 10.50 by hand
Every other format follows from the decimal price in one step. Implied probability is one divided by 10.50, which gives 9.52%. American odds depend on which side of 2.00 the price sits: at or above 2.00, multiply (10.50 − 1) by 100 to get +950. The fraction is 10.50 − 1 written as a ratio and snapped to the nearest traditional price, 19/2. A prediction market simply quotes the probability in cents: 10¢.
The vig at 10.50
If both sides of a two-way market were 10.50, their implied probabilities would sum to -80.95% above 100%. That is the overround; as a share of stakes it is a -425.00% margin. The fair price with the margin removed is 2.00 on each side. The devig calculator does this for any market and any method.
