The bag contains two times the red marbles as blue ones. So, R=2B. It also contains two times the blue marbles as green ones. So, B=2G. So if we consider, G to be 2, we get B as 4 and R as 8. Now the total outcomes: 14. Chances of getting blue: 4. Hence probability of getting blue: 4/14 = 2/7. Hence, D is the answer. Posted from my mobile device Jun 06, 2010 · Now, the total number of marbles in the bag is 3 + 2 + 3 = 8. Therefore, the probability that the second marble drawn is blue is 2/8 = 1/4. Now, the total number of marbles in the bag is 3 + 1 + 3... A bag contains 4 green marbles, 6 red marbles, and 2 white marbles. A bag contains 4 green marbles, 6 red marbles, and 2 white marbles. Three marbles are drawn at random with replacement. With replacement means that after a marble is drawn, it is replaced before the next one is drawn. What is the probability of not green, not red, not white? A bag contains 7 blue marbles, 5 red marbles, and 9 green marbles. A bag contains 7 blue marbles, 5 red marbles, and 9 green marbles. A Bag Contains 8 Marbles of Which 3 Are Blue and 5 Are Red. One Marble is Drawn at Random, Its Colour is Noted and the Marble is Replaced in the Bag. - Mathematics
