W-by-Al ratio

here's a puzzle I asked our TSOtool team a few months ago:

Let there be 2 contestants in an election, say W and Al, and Al wins by getting n votes to W's m votes (n > m). What is the probability that as each vote is counted, Al is always ahead of W ? i.e. after every step of the counting, Al has to have more votes than W. Assume votes are counted in random order. Never mind that W becomes president instead.
