Answer to Question 1

d
RATIONALE: When formulating a constraint, the units of measurement on the left-hand side of the constraint must match the units of measurement on the right-hand side.

Answer to Question 2

1/12 or 0.0833 or 8.3
RATIONALE: The probability of rolling a sum of 11 corresponds to the event (6, 5), (5, 6) which is 2 out of 36 = 2/36.
The probability of rolling a sum of 12 corresponds to the event (6, 6) which is 1 out of 36 = 1/36.
Using the addition rule we add the two we have 2/36 + 1/36 = 3/36 = 1/12.
