I think the snarkiest comment I heard to this effect was that if the schools DID teach probability, they'd lose their lottery money.

I also ran across an article that stated that the method we use to teach math isn't just guarenteed to get people to hate the subject, it's ass-backward.

The equivalent for music teaching in school would involve teaching children how to carefully draw notes and scales up through high school. Teachers would be annoyed by children who are distracted from their music education by actually singing or whistling.
