5/17
Non red marbles are 12 + 5 = 17.
So the ratio is 5/17.
A Bag contains 3 blue marbles, 2 red marbles, and 4 green marbles. Mark reaches in and randomly selects a marble. He replaces it, and randomly selects another. What is the probability that both marbles were the same color? What is the probability that 1 was red and the other was green?
