Or do they look at your mark for your HSC exam and then compare it to your year group and use this to estimate your assessment mark? I'm getting told different things by everyone. Some of my teachers say that 'it's not the mark that matters, it's the rank.'
I think my question is a bit...
Find the number of arrangements
possible if x people are
a) in a straight line with 3 people together
b) in a circle with 2 people not together
The answer for a is 3!(x-2)! and the answer for b is (x-3)(x-2)! Can somebody please explain why? Thanks so much :)
