How To Calculate The Value Of Npr Using Functions

How to Calculate the Value of nPr

Use the following permutation formula to calculate the value of nPr:

Where:

Problem Statement

You’re given the values of n and r. You need to calculate the value of nPr.

Example 1: Let n = 10 and r = 5.

Therefore, nPr = 10! / (10-5)! = 10! / 5! = 30240.

Thus, the output is 30240.

Example 2: Let n = 3 and r = 2.

Therefore, nPr = 3! / (3-2)! = 3! / 1! = 6.

Thus, the output is 6.

Example 3: Let n = 8 and r = 0.

Therefore, nPr = 8! / (8-0)! = 8! / 8! = 1.

Thus, the output is 1.
