Actually, the probability is 100% that the elevator
will be going in the right direction.  Proof by induction:

N=1.    Trivially true, since both you and the elevator
        only have one floor to go to.

Assume true for N, prove for N+1:
        If you are on any of the first N floors, then it is true by the
        induction hypothesis.  If you are on the N+1st floor, then both you
        and the elevator have only one choice, namely down.  Therefore,
        it is true for all N+1 floors.
