Well I know that Houston has over 4 million people and Chicago is slightly larger than Houston

I think I heard that redheads account for 2% of the population but maybe it's as high as 5%, we'll say for shits

About a fifth of the population is in grade school which I would assume accounts for the majority of tutorees, the rest being negligible.

I'd estimate that maybe .5 kids out of every class play piano, and that a tutor has on average 10 tutorees

Ballpark, about a hundred.

How'd I do?

dam it all to heck

i did some intense research, looking at craigslist for chicago and san diego, for both redheads and piano tutors.

and while chicago prob has more redheads, sandiego has more piano tutors

therefore. probably 60-100 redhead pianus tutors in chicago
