We know there are 55 total games in the tournament so keep that in mind.

1. There are 5 left-handed players and 5 right-handed players so each left-handed player will play 5 right-handed players so there are 5*5 matches in there so it is **25**.

2. Well, that would just be 4+3+2+1 left-hand only matches which will add up to **10** rounds.

3. It would be the same as the left-handed players which is 10/55 which simplifies to **2/11**.

4. Anita will play 9 games so it is **9/55** which cannot be simplified.
