Make it easy, keep 'em busy - law of large numbers illustrated

They say: Use the "Simulating the Probability of Head With a Fair Coin" applet on the text CD or other software to illustrate the long-run definition of probability by simulating short-term and long-term results of flipping a balanced coin (Agresti and Franklin, p.216)

I say: Since it is not explained how to use "other software", the readers are in fact forced to use the applet from the text CD. This is nothing but extortion. This exercise requires the students to write down 30 observations (which is not so bad, I also practice this in a more entertaining way). But the one following it invites them to simulate 100 observations. The two exercises are too simple, time consuming and their sole purpose is to illustrate the law of large numbers introduced on p. 213. The students have but one life and the authors want them to lose it for AP Statistics?

The same objective can be achieved in a more efficient and instructive manner. The students are better off if they see how to model the law of large numbers in Excel. As I promised, here is the explanation.
