thanks for your time! Answer by Nate(3500) (Show Source):
You can put this solution on YOUR website! blue marbles: 3
red marbles: 6
total marbles: 9
Chances of drawing a red marble: 6/9 or 2/3
Chances of drawing a red marble when you replace the first: 6/9 or 2/3
Chances of drawing a blue marble when you replace second: 3/9 or 1/3
(2/3)(2/3)(1/3) = 4/27
