- The calculator will show both:
- Permutation (P(n, r)): The number of ways to arrange
r
items out ofn
items where the order matters. - Combination (C(n, r)): The number of ways to choose
r
items out ofn
items where the order doesn’t matter.
- Permutation (P(n, r)): The number of ways to arrange
- Reset:
