 a. proportionality b. divisibility
  c. additivity d. negativity

Question 2

Answer to Question 1

b
RATIONALE: In a linear programming model, the assumption divisibility means that the decision variables are continuous. The divisibility assumption plus the nonnegativity constraints mean that decision variables can take on any value greater than or equal to zero.

Answer to Question 2

5/44
RATIONALE: The events are dependent therefore the probability is calculated as P(red then purple) = P(red)  P(purple) = 3/12  5/11 = 15/132 = 5/44
