The Scout’s Notebook
American, decimal, and fractional odds are three notations for the same price, and the bridge between them is implied probability: decimal odds = 1 ÷ implied probability, so −110 = 1.91 decimal = 10/11 = 52.4%.
Implied probability is the number that matters: it is what the price says the outcome's chance is, before the book's margin is considered.
−110 means you must risk $110 to win $100, which is 1.91 in decimal odds and a 52.38% implied probability. The extra 2.38 points over a coin flip is the sportsbook's margin on a standard two-sided market.
