You can put this solution on YOUR website!
See this video for a nice look at this type of problem. http://collabvsl.wetpaint.com/page/Basic+Probability
In this case, you have a total of 5%2B3%2B1=9 marbles.
The odds of drawing a blue marble are 3%2F9 = 1%2F3
So the odds of drawing a 'non-blue marble is 1+-+%281%2F3%29 = 2%2F3
