FAQ
- How do you convert decimal odds to implied probability?
- Divide 1 by the decimal odds and multiply by 100. For example, 2.50 decimal odds is 1 / 2.50 = 0.40, or a 40% implied probability.
- What do +150 and -200 American odds mean?
- A positive number is the profit on a 100 stake: +150 returns 150 profit plus your 100 back. A negative number is the stake needed to win 100: -200 means risking 200 to win 100.
