Probability from Odds Formula:
From: | To: |
The probability derived from betting odds represents the implied probability that a particular outcome will occur, as suggested by the odds. It's a crucial concept in sports betting and statistical analysis.
The calculator uses the simple formula:
Where:
Explanation: The formula converts decimal odds to their implied probability percentage. For example, odds of 2.00 imply a 50% probability.
Details: Understanding implied probability helps bettors assess value in betting markets and make more informed decisions about potential wagers.
Tips: Enter decimal odds (must be 1.01 or greater). The calculator will instantly show the implied probability as a percentage.
Q1: Why can't odds be less than 1.00?
A: Decimal odds below 1.00 would imply a probability over 100%, which is mathematically impossible for a single event.
Q2: How do fractional odds compare?
A: First convert fractional odds to decimal (e.g., 5/1 = 6.00 in decimal) before using this calculator.
Q3: What does 100% probability mean?
A: This would be a "sure thing" with odds of exactly 1.00, which never occurs in real betting markets.
Q4: Why do bookmakers' probabilities add to more than 100%?
A: The excess (overround) represents the bookmaker's margin or vigorish.
Q5: How accurate are these probabilities?
A: They represent the bookmaker's assessment including their margin, not necessarily true probabilities.
