Is it really a question of focus, though? At my high school (Texas public school), Calculus and Statistics were both optional AP courses. You can usually choose whether or not to take whichever combination you want. Some people took neither. I took both. If high schoolers had to take one advanced class, I think it should be discrete math. Keeps their algebra skills sharp, introduces them to proofs, and still introduces them to basic probability. Obviously the availability of this offerring makes this impractical at the moment.
