Let’s Begin…

You’re the chief advisor to an eccentric king who needs to declare his successor. He wants his heir to be good at arithmetic, lucky, and above all else, honest. So he’s devised a competition to test his children, and ordered you to choose the winner. The future of the kingdom is in your hands. Can you find the worthiest successor? Dan Katz shows how.

Suppose that another competition used 20 rolls of a different pair of dice: one with the numbers 1, 3, 5, 7, 9, and 11; and one with the numbers 3, 5, 7, 9, 11, and 13. If these were the four scores in this competition, which one should be declared the winner?
