Answer to Question 1

a
RATIONALE: In problem formulation, the objective is expressed in terms of the decision variables.

Answer to Question 2

0.1667 or 16.7 or 1/6
RATIONALE: The probability of an event is equal to the sum of the probabilities of outcomes for the event. The probability of rolling a seven corresponds to the event (6, 1), (5, 2), (4, 3), (3, 4), (2, 5), (1, 6) which is 6 out of 36 = 1/6.
