Answer:

The answer would be A 1/15.

Step-by-step explanation:

The answer is 1/15 because you have 10 marbles in all and 3 of those 10 marbles are white. You get 3/10 and than since it does not say that it was replaced you take one white marble away which would give you 2/9. so you take 3/10 * 2/9 = 1/15 (when everything is simplified)

Hope this helps to explain it! :)
