Use a random-number table or random-number generator to simulate tossing a fair coin 10 times. Generate 20 such simulations of 10 coin tosses. Compare the simulations. Are there any strings of 10 heads? of 4 heads? Does it seem that in most of the simulations half the outcomes are heads? half are tails? In Chapter 5, we will study the probabilities of getting from 0 to 10 heads in such a simulation.
