What this tool calculates
Estimate BTTS Yes and No probabilities from the chance that each team scores at least once.
Under the independence assumption, P(BTTS Yes) = P(home scores) × P(away scores). BTTS No is the complement.
Results are informational. Actual limits, deductions, voids and settlement can vary by operator and jurisdiction.
Worked example
If the home team has a 75% chance to score and the away team 60%, BTTS Yes is estimated at 45%, with fair decimal odds of about 2.2222.

Tips and limitations
- Use estimates from one consistent source and market definition.
