Frequently Asked Questions
Permutation (nPr) and Combination (nCr)
These functions make it possible to perform permutation and combination calculations.
n and r must be integers in the range of 0 ≦ r ≦ n < 1 × 1010.
Example: To determine the number of permutations and combinations possible when selecting four people from a group of 10.
Permutations:
- 10
(nPr) 4
Combinations:
- 10
(nCr) 4
