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%
