How to Use the Probability Calculator (Step by Step)

1. Enter the total number of possible outcomes (e.g., 6 for a dice roll).

2. Enter the number of favorable outcomes (e.g., rolling a 4 means 1 favorable outcome).

3. Click “Calculate” to get the probability.

4. The result will show the fraction, decimal, and percentage probability.

5. For advanced users, enter multiple probabilities to calculate combined events (AND/OR).

Example: The probability of rolling a 6 on a dice = 1/6 = 0.1666 = 16.67%.
