Coin tossing simulation illustrating law of large numbers
---------------------------------------------------------

heads [, SAVE ]


heads    simulates the tossing of a coin.  Via the dialog box, 
         you can choose the number of trials, the number of 
         coins per trial, and the probability of a head for each
         coin.  A graph is then shown with the number of trials
         on the X axis, and the average number of heads on the
         Y axis.  As the number of trials increases, you can
         see the average number of heads approach the expected
         number of heads, illustrating the law of large numbers.

         If you choose the "Show Conf. Interval" option, you can
         also view a confidence interval for the average number
         of heads.
