What does 2.00 odds mean?
Decimal odds of 2.00 imply a simplified probability threshold of 50%. The calculation is 1 ÷ 2.00 = 0.50. For a selection to have estimated edge, your assessed probability must be above that threshold after considering margin, risk and the quality of the estimate.
Practical meaning
At 2.00 odds, a winning selection returns the original stake plus gross profit equal to the stake, before any taxes or adjustments.
Why the threshold is not perfect
The bookmaker includes margin, so the market does not provide a pure probability. The formula is a starting point, not an exact prediction.
How Betty uses it
Betty compares the threshold implied by the odds with its internal estimate and context to decide whether the difference deserves attention.
