Discover the total number of possible outcomes for your events with our versatile online calculator. Calculate permutations (order matters) or combinations (order doesn't matter) quickly and accurately. Ideal for students, statisticians, and data analysts.
Formula:
Use this calculator to find the number of possible outcomes. Depending on whether the order of selection matters, you can choose between:
- Permutations (Order Matters): P(n, r) = n! / (n - r)!
- Combinations (Order Doesn't Matter): C(n, r) = n! / (r! * (n - r)!)
Where:
- n = total number of items available
- r = number of items to choose from the set
- ! denotes the factorial (e.g., 5! = 5 × 4 × 3 × 2 × 1)
