Decision Trees - The One Course That Everybody Should Have Before Graduation

If i could go to all high schools and just say, what is the the one course that every one should have before they graduate in in the math and sciences areas, it would be statistics. Because we live in a probablistic world when our brains aren't wired for even people trained in statistics and probability make probablistic errors all the time. Se for whatever evolutionary reason, we don't naturally think that way. And so you can make the right decision and still have a bad outcome.
