Sportsbooks bake a margin — the vig or juice — into every market. On a coin-flip priced -110/-110, the two implied probabilities sum to ~104.76%, not 100%. That extra 4.76% is the book's edge.
To find the fair (no-vig) price, we convert each side to implied probability, sum them, and divide each side by that sum. Converting the normalized probability back to American odds gives you the true price a bet should be at.
Compare that fair price to what you can actually bet. If your book's price is longer than fair, you've found a +EV bet — over time, that's how bettors beat the book.
Two-way vs three-way markets
Use two-way for spreads, totals, most player props, and moneylines in sports without draws (NFL, NBA, MLB, tennis). Use three-way for soccer moneylines and any market where a draw is a possible outcome.
