**Damon**, Sunday, March 14, 2010 at 8:20pm11 marbles, 5 green

probability that #1 is green = 5/11

now 10 marbles, 4 green

probability that #2 is green = 4/10

now 9 marbles, 3 green

probability that #3 is green = 3/9

so

5/11 * 2/5 * 1/3

= 2/33

**keisha**, Sunday, March 14, 2010 at 8:42pmthanks what is the probability that at least one of the marbles drawn is green? I thinks it's 1/11 but not sure.

Then what is the probability that only one of the marbles drawn are green?
