If that is true then you would not have been given the question. Now would have been?
What topics in you text material go with this question?

i got it one more to go

the answer is 1307674368000 right?

It depends on the definiton of "different arrangement". Is a rotation around 120° a different arrangement? Is a mirrored setup a different arrangement? If both count as different, this is correct.

15!

15! = 1307674368000
