Simple permutation

  1. Jun 3, 2009 #1
    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.

    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!
