One bag contains 5 red marbles, 4 blue marbles, and 3 yellow marbles, and a second bag contains 4 red marbles, 6 blue marbles, and 5 yellow marbles. If Lydia randomly draws one marble from each bag, what is the probability that they are both not yellow?

5 answers

  1. The two draws are independent.
    So the probability of getting a yellow in both bags is the product of the probability of getting a yellow in each bag.

  3. 1/12

  4. The question asks the opposite... not yellow.
    so 9/12 * 10/15 = .75 * .666 = 50%

  5. Andrew has it right.
