I am on route 25 in Kanto, which means I got the national dex. On this route, I am looking for a venonat. I will record what pokemon I see and you guys can do the math until I find the one I need.

1. Pidgey
2. Bellsprout
3. pidgey
4. pidgey
5. pidgey
6. bellsprout
7. pidgey
8. pidgey
9. abra
10. pidgey

okay of these 10, what is the percentage of pokemon?

There sure are a lot of pidgey here.
