Question

What is the number of ways to arrange 8 objects from a set of 12 different
objects?

Answer 1

19958400 ways

Explanation:

As the question involves arrangement, permutation will be used.

P(n,r) = n! / (n-r)!

Here

n=12

and

r = 8

So,

P(12,8) = 12!/(12-8)!

= 12!/ 4!

=19958400 ways

Therefore, the 8 objects from 12 can be arranged in 19958400 ways ..
