How it works
Plus odds show the profit on a $100 bet: +150 wins $150. Minus odds show what you bet to win $100: -150 risks $150 to win $100.
Decimal odds are the total payback per $1, stake included: +150 is 2.50, -150 is 1.67.
Implied probability is 1 / decimal odds. It includes the book's margin, so a market's implied probabilities add up to more than 100%.
