how many ways 15 student can be sit where 2 talkative students never sit together?
Are they sitting in a row or in a circle or what?
15P2 = 210
210 ways
Max that is not correct.
Plus you need to state the seating arrangment.
If they were sitting in a circle then the answer would be
14! - 2*13! =
14!-2*13! = 74 724 249 600
Oh and that is if rotations are counted as the same !
