Not sure if anyone linked it here, but my favorite simulator was a 2D grid, with about 50 or so units per side. The computer picks 3 squares, you pick 3 squares. The XxY unit grid was set up such that if you picked the same 3 squares as the computer, it was the same odds as winning Powerball. Seeing how hard it was to even get 1 square really drove home the odds. I also did a similar calculation by estimating the area of millions of quarters (enough to represent the 1/N chance to win) and thought "ok, if I launched a rubber ball randomly at high velocity in this huge room, I would win if it landed on one exact quarter that I picked in advance. When I saw it like that, I realized there's no way.
