If a>b, A has already more heads than B hence A has more heads than B once the result of the 9th coin is added, and A wins.

(either..or of these two. Because AND case cannot happen..(he has only one coin more than B)).
If former is the case, A wins.
With the latter, B wins. (Think about it).
Both of which are equally likely.
