Using Calculation Modes
Technical Information
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 1: To determine how many different 4-digit values can be produced using the numbers 1 through 7
Numbers cannot be duplicated within the same 4-digit value (1234 is allowed, but 1123 is not).
- 7
(nPr) 4
- 840.
Example 2: To determine how many different 4-member groups can be organized in a group of 10 individuals
- 104
- 210.
