I finished high school in the first year of a new assessment system in South Australia. This of course resulted in curriculum changes and all that kind of fun that happens around these kind of things. One of the objections parents raised was that the maths curriculum was too hard. As a child of two mathematicians I got to hear more about this as one of my parents was in the process of actually becoming involved in various aspects of the high school maths curriculum and how it was examined. One of the areas singled out as being too difficult was probability, you know calculating the chance of something happening. So the Authorities decided to remove it. What was funny to those of us who knew what was going on was that they didn't remove counting.
Counting is the process by which we work out how much of something there is. There are ways to do this mathematically, combinations and permutations and all that jazz. The joke here is that probability, at least in the way the course was structured, involved counting
