Michelle puts 7 red marbles and 5 blue marbles into a bag. If two marbles are chosen at random from the bag, one by one, without replacement, find the probability that two blue marbles are chosen. \( \begin{array}{ll}\text { A } \frac{25}{144} & \text { C } \frac{7}{22} \\ \text { B } \frac{49}{144} & \text { D } \frac{5}{33}\end{array} \)

4. A box contains a total of 100 CDs that were manufactured on two machines. Of them, 60 were manufactured on Machine I. Of the total CDs, 15 are defective. Of the 60 CDs that were manufactured on Machine I, 9 are defective. Let \( D \) be the event that a randomly selected CD is defective, and let A be the event that a randomly selected CD was manufactured on Machine I.
