Well, first you have to determine the probability of only drawing a yellow marble. To do that, you have to add all the marbles of all the colors together and make a ratio with that as the demoninator and the yellow marbles as the numerator.

1/30 to 8/30?

8/30 is the probability of drawing a yellow marble. Now you have to multiply that number by itself.
