Assuming the original assumption of independence, the odds of only picking 1 or less musicians in 40 picks is around 30%.

I am not quite sure where you are going with this. My premise is that because we teach math to everyone for every year the demand for math teachers is 10x the demand for music teachers and this fact does indeed dilute mathematical talent and skill in the ranks of teachers. I was already assuming the talent pools, be they 2% or 5%, were similar.

If all of this is to my question "Who here has taken a math class and who here has taken a music class?" the path you are following is irrelevant. I could type that same question in a blog about brick laying or fishing (in the U.S.) and every one will still raise their hand when I ask if they take math classes, and not raise their hand when I ask if they take music classes. We teach math constantly from kindergarten to halfway through college.

Why?
