The calculator uses the formula:
Where:
Explanation: This formula provides the reciprocal relationship between odds in favor and odds against, allowing conversion between these two probability expressions.
Details: Understanding and converting between different odds expressions is crucial for probability analysis, gambling calculations, risk assessment, and statistical modeling in various fields.

Q1: What's the difference between odds in favor and odds against?
A: Odds in favor represent the ratio of winning outcomes to losing outcomes, while odds against represent the ratio of losing outcomes to winning outcomes.
Q2: Can odds in favor be less than 1?
A: Yes, odds in favor can be less than 1, indicating that unfavorable outcomes are more likely than favorable outcomes.
Q3: How do odds relate to probability?
A: Probability of success = Odds in favor / (1 + Odds in favor), while probability of failure = Odds against / (1 + Odds against).
Q4: What does odds against of 2:1 mean?
A: Odds against of 2:1 means there are 2 unfavorable outcomes for every 1 favorable outcome, indicating the event is twice as likely to fail as to succeed.
Q5: When is this conversion most useful?
A: This conversion is particularly useful in gambling scenarios, sports betting, risk analysis, and any situation where probability expressions need to be converted between different formats.
