Definition: This calculator converts moneyline odds into their implied win probability percentage.

Purpose: It helps bettors and analysts understand the true probability implied by moneyline odds in sports betting.

2. How Does the Calculator Work?

The calculator uses different formulas for positive and negative moneylines:

\[ P = \begin{cases} \frac{100}{ML + 100} & \text{if } ML > 0 \\ \frac{-ML}{-ML + 100} & \text{if } ML < 0 \end{cases} \]

Where:

$ P $ — Implied win probability (decimal)
$ ML $ — Moneyline odds (positive or negative)

Explanation: For positive odds, probability is calculated differently than for negative odds due to their different risk/reward structures.
