SOURCE: how do i calculate permutation in fx-82ms casio

Hello,

Find on the calculator the [nPr] key either (you may have to use the [2nd] or [2ndF] key) then
1. Enter the number that corresponds to n eg. 18
2. Press the [nPr] key
3. Enter the number that corresponds to r eg. 5

18[nPr]5 gives 1028160

If you calculate combinaitions use [nCr] key.

Hope it helps
