Tell whether the events are independent or dependent. Event A: Brooke picks 23. Event B: Shari picks 88. O dependent None of the other answers are correct O independentQuestion 5 0 / 1 pts A bag contains hair ribbons for a spirit rally. The bag contains 3 black ribbons and 17 green ribbons. Lila and Jessica are drawing from the bag at random. Explain why the events are dependent. Then find the indicated probability. Lila selects a black ribbon and puts it in her hair, and then Jessica selects a green ribbon. Express your answer as a fraction in simplest form. O The events are dependent because P(Jessica green) is different when Lila has already removed one ribbon from the bag. 17 190 D The events are dependent because P(Jessica green) is the same when Lila has already removed one ribbon from the bag. O The events are dependent because P(Jessica green) is the same when Lila has already removed one ribbon from the bag. 51 400 ONone of the other answers are correct O The events are dependent because P(Jessica green) is different when Lila has already removed one ribbon from the bag. 51 380Question 6 D f 1 I31:5 There are 7" yellow, 5 green, and 3 blue party hats in a bag.
