A bag contains 3 green marbles and 6 blue marbles. What is the probability of drawing a blue marble, then another blue marble, then a green marble, replacing the marble after each draw?
Well, adding all the marbles together, 3 green marbles and 6 blue marbles, you would get 9 marbles in the bag altogether. If you place the marble back into the bag after drawing it, the probability of getting a green marble would be 3/9, or 1/3 of the bag. If you wanted to get a blue marble, your chances of getting it would be 6/9, or simplified, 2/3. I hope that helps :)
