Challenge Problem: Pepys Problem
Samuel Pepys posed this problem to Issac Newton - which is more probable
at least one throw of a 6 in six throws of a fair die or at least two
6's in twelve throws of a fair die? We do not know what Newton's response
was. But you are going to give a computational estimate what the two
probabilities are.
