A bag contains 6 blue marbles, 4 red marbles, and 2 yellow marbles. What is the possibility of selecting a blue marble, replacing it, then selecting another blue marble
1/4 or 25%. Since there are 12 marbles all together, and there are 6 blue marbles, the probability of choosing a blue marble is 1/2. Because you are replacing the marble, you multiply 1/2x1/2 and get an answer of 1/4, which equal 0.25 or 25%.
