simple permutation

There are 8 people in a line to see a movie.
A,B,C are in the line.
What is the probability that A is in between B and C?

(I can explain more, but don't want to throw in too much to confuse).
BTW there is 8 people in the line.

Re: simple permutation

Could you answer if only A, B, and C were in line?

Here's another hint. Is there anything "special" about A?

I notice it has been 3 hours since you asked this. In that time you could have listed all possible lines and counted how many have A between B and C!
