Where:
Explanation: For a 10% probability (0.1 in decimal), the calculation would be (1/0.1) - 1 = 9, meaning the odds are 9 to 1.
Details: Understanding how probability translates to odds is crucial for sports betting, risk assessment, and comparing different betting opportunities.
Tips: Enter the probability as a percentage (e.g., 10 for 10%). The calculator will automatically compute both decimal and fractional odds.
Q1: What does 10% probability mean in betting terms?
A: A 10% chance translates to 9.0 in decimal odds or 9/1 in fractional odds.
Q2: How do I convert decimal odds back to probability?
A: Probability = 1 / (Decimal Odds + 1). For 9.0 odds: 1/(9+1) = 0.1 or 10%.
Q3: What's the difference between decimal and fractional odds?
A: Decimal odds show total return per unit bet (including stake), while fractional shows profit relative to stake.
Q4: Why would I need to convert probability to odds?
A: To compare your estimated probability with bookmakers' odds to find value bets.
Q5: What's the relationship between probability and odds?
A: Odds represent the ratio between the probability of an event occurring and not occurring.
