Getting Started is a fast-paced introduction. Read the chapter for details.
Suppose you want to model flipping a fair coin 10 times. You want to track how
many of those 10 coin flips result in heads. You want to perform this simulation
40 times. With a fair coin, the probability of a coin flip resulting in heads is 0.5
and the probability of a coin flip resulting in tails is 0.5.
