Question

Evaluate the expression. 10p5

Answer 1

The correct answer is

30,240

Answer 2

So this is permutation.

The number of permutations of n objects taken r at a time is defined as
`_nP_r = (n!)/((n-r)!)`.

Here, you have 10 objects and 5 of them will be taken.

So that would be 10! / (10-5)! = 10! / 5! = 30240

Final answer: 30240

Hope this helps.
