Scenario 4-2 Let the sample space for an event be S' = (1, 3, 5,7,9, 11, 13, 15) and let the events A and & be defined as follows: A = (3,5,7) B = (5,7,9, 11, 13} Question 5 (1 point) Refer to Scenario 4-2. Which set represents An B? O a (5, 7 } O b (3,5, 7,9, 1 1, 13} O c (1, 3, 5, 7, 9, 1 1, 13, 15} O d (3,5, 7} O e {1, 15 } Question 6 (1 point) Refer to Scenario 4-2. Which set represents A V B? O a {1, 3, 5, 7, 9, 1 1, 13, 15} O b {3, 5, 7, 9, 1 1, 13} O c {1, 15) O d {3, 5, 7} O e (5, 7)
