Thank you! Can you explain how you got that though?

anonymous · Answer

it occurs to me that you can calculate separately the probability of drawing a green marble, a red marble and a yellow marble, and then do the following:
p(red)*p(yellow)+p(red)*p(green)+p(yellow)*p(green)

Find the probability of drawing two of what kind of marble?
You must have cut off more than just the f at the beginning.
