Probability Formula
Ratio of favorable outcomes to total possible outcomes.
P(A) = n(A) / n(S)
- n(A): Number of Favorable Outcomes
- n(S): Total Sample Space
Example 1
Rolling a specific number (e.g., 6) on a die.
- Favorable: 1 (the face '6')
- Total: 6 (faces 1-6)
- P = 1/6 ≈ 0.1667 (16.67%)
How to Use
