Errors with 200 Dice
Let us consider the case of rolling 200 Dice and summing the spots. This will lead to a result between 201 and 1200 with an average of 700.
Subtracting 200, we get the equivalent of 1000 people with a poll whose result is 50% yes and 50% no. Any one summing of 200 Dice will not get 700 but a value near this. The applet does this process a number totalFrq times and plots the result as a histogram or frequency plot of dice sums.
