Am after a few stats for toying around with, if someone with a database could shed some light would be great.

1.)What percent of races are won by horses paying $15 and under?
2.)What percent of all races are won by horses with a odd numbered TAB saddlecloth?
3.)And what percent of question one are won by horses with a odd number?

What I am hoping to achieve with the stats? Well, even Im unsure about that
