I Jos,

I should have said when playing craps. This involves rolling two dice and provide 36 probabilites (e.g. 6^2). There are more combinations that make seven than any other number as follows:

    dice 1    dice 2
    ------    ------
      1          6
      2          5
      3          4
      4          3
      5          2
      6          1

There are six combination you can roll to make sever. Contrast this with snake eyes or box cars. They can only be made in one combination as follows:

    dice 1    dice 2
    ------    ------
      1         1      snake eyes
      6         6      box cars

If you rolled an honest pair of dice 1000 times, and recorded the number of time each number was hit, you could then graph the result with the numbers 1 through 12 going across the botton horizonally, and the occurrences going up the graph vertically. When the results are plotted, you should find that you have a perfect bell curse. Of course shake eyes and box cars would be at the two extremes of the graph with the lowest number of occurrences
