Question

Early studies of probability were conducted by the Italian mathematician Girolamo Cardano (1501-1576). One of the many dice games that Cardano studied was played with six 6-sided dice. Each of these six dice had five blank faces and one face with a number. The numbers 1 through 6 each appeared on one of the six dice. All 6 dice were rolled at once, and the payoff to the gambler was based on the sum of the numbers showing on the up faces. What is the expected value of the sum obtained by rolling all 6 dice? 3 3.5 6 36 It cannot be determined from the given information

Explanation / Answer

(E) It cannot be determined form the information given, becausewe do not know what numbers were written on the five dice that didnot have all 6 faces covered with numbers. For all we know, 1 ofthem has a 53 on it, which would affect the expected value of thesum of the dice.
