How to Use the Probability Calculator
Calculate the probability of single and combined events.
- Enter the number of favorable outcomes.
- Enter the total number of possible outcomes.
- See the probability as a fraction, decimal, and percentage.
Probability Formulas
Single Event
P(A) = favorable / total
Outcomes you want divided by all equally likely outcomes.
Example:
Input: rolling a 6
Calculation: 1 / 6
Result: ≈ 16.7%
Independent Events (AND)
P(A and B) = P(A) × P(B)
Multiply probabilities of independent events.
Example:
Input: two heads
Calculation: 0.5 × 0.5
Result: 25%
Real-World Use Cases
