If you only want the average, you're best off calculating that and displaying
it. I'd do such a program by having a variable ("x"). Then, for
every toss, change x to
[old value of x]*number_of_tosses_excluding_this_one + outcome_of_this_toss
---------------------------------------------------------------------------
number_of_tosses_including_this_one
Make a loop to toss a coin, display the value of the variable, then loop back
until the user interrupts the procedure. If the value approaches 1/2, you can
conclude that the probability of getting heads is equal to the probability of
getting tails.
Of course, you'd have to include the reasoning behind this formula in your
report, but it shouldn't be hard to grasp.
