Example Calculations
Example 1: Basic Probability
If you have 3 successful outcomes out of 10 total outcomes:
- Probability = 3/10 = 0.3
- Percentage = 30%
- Odds = 3:7
Example 2: Percentage Conversion
If the value is 75%:
- Probability = 0.75
- Fraction = 3/4
- Odds = 3:1
Example 3: Multiple Events (AND)
If:
- Event A = 0.5
- Event B = 0.4
Then:
- Combined probability = 0.5 × 0.4 = 0.2
- Percentage = 20%
Example 4: Odds Conversion
If odds are 2:3:
- Probability = 2 / (2+3) = 0.4
- Percentage = 40%
