(12C Platinum) Combination Permutation

[Gamo]

This program is from HP 12C Platinum Solutions Handbook.

To solve for Combination and Permutation the "Flags"
is use instead of manually go to [GTO] xxx
to go to specific program line.

Enter 0 to calculate Combination
Enter 1 to calculate Permutation

---------------------------------------------------

Procedure:

0 [R/S] display 0 // for Combination

m [=] n [R/S] display Answer for Combination
----------------------------------------------------
1 [R/S] display 1 // for Permutation

m [=] n [R/S] display Answer for Permutation
----------------------------------------------------

Example:

5C3

0 [R/S] display 0 // calculate Combination

5 [=] 3 [R/S] display 10

-----------------------------------------------
11P4

1 [R/S] display 1 // calculate Permutation

11 [=] 4 [R/S] display 7920
