If you place 3 marbles in each box then the probability is always one half or 50%. If you do not put exactly 3 marbles in each box, the probability will become less than 50%. It does not matter what colors of marbles you put in each box.
It is 2/10.
The chance is 25%.
There would be a 7/19 or 36.84% chance of drawing a blue marble from the bag.

The chance of pulling a red marble from a bag without looking depends on the total number of marbles and the number of red marbles in the bag. If there are, for example, 5 red marbles and 15 total marbles, the probability would be 5 out of 15, or 1 in 3. To find the exact probability, divide the number of red marbles by the total number of marbles.
marbles were originally made from the stone, marble. so even after people started making them out of glass they kept the name marbles. I have an old marble marble.
12 white marbles from (7+3+12) = 22 marblesChance of a white marble on first pick = 12/22 = 6/11.Chance of a white marble on second and third picks are the same, as the marble is replaced.So, the chance of a white marble three times is 6/11 * 6/11 * 6/11 = 216/1331 = approximately 16.23%
3/6 * 3/5 = 6/30 or 1/5 so you have a 20% chance of pulling a white and then black marble.
