How it works
For negative odds (favorites): implied probability = |odds| / (|odds| + 100) x 100. So -110 gives 110/210 = 52.38%. For positive odds (underdogs): 100 / (odds + 100) x 100. So +150 gives 100/250 = 40%.
This is the book's implied probability, which includes the vig. If you add up both sides of a market, you get more than 100%, with the difference being the sportsbook's edge. Use the Vig Calculator to see the fair no-vig probability.
