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

objects?

19958400 ways

Step-by-step 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 ...
