A bag contains 3 red marbles, 4 blue marbles, and 6 green marbles. Which pair of events are complementary events? A) choosing a
blue marble; choosing a green marble B) choosing a red marble; choosing a marble that is not blue C) choosing a blue marble; choosing a red marble D) choosing a green marble; choosing a marble that is not green
Complementary events are those events that are opposites of each other. i.e. in this case the complementary event for choosing a green marble is not choosing a green. It has nothing to do with choosing or not choosing marbles of colors other than green.
