Two fair dice are rolled. Let B = the event that the sum is odd, A = the event that the sum is 7 or more, and C= the event that at least one die shows a 2. For these three events, which pairs of events are independent and which pairs are dependent? ..... How can pairs of events be shown to be independent? O A. Events E and F are independent when P(E|F) = P(E) and P(F|E) # P(F). O B. Events E and F are independent when P(E|F) # P(E) and P(F|E)#P(F). OC. Events E and F are independent when P(E|F) = P(E) and P(F|E) = P(F). O D. Events E and F are independent when P(E|F)#P(E) and P(F|E) = P(F). Which pairs of events are independent? Select all that apply. O A. events A and C O B. events B and C O C. events B and A O D. No pairs are independent. Which pairs of events are dependent? Select all that apply. O A. events B and C O B. events A and C O C. events B and A D. No pairs are dependent. O O O O
