Answer to Question 1

a
RATIONALE: The proportionality assumption necessary for a linear programming model to be appropriate, means that the contribution to the objective function and the amount of resources used in each constraint are in accordance to the value of each decision variable.

Answer to Question 2

10/121
RATIONALE: The events are independent, so the multiplication law for independent events can be used to calculate the joint probability.

P(red then purple) = P(red)  P(purple) = 2/11  5/11 = 10/121
