You have to do a tree diagram I can't show u but all I can tell u is u have to add all the marbles together to make 20 and the first part to the question is 6/20 but u have to take away 2/20 overall the answer could be 3/20 averaging it but this is estimated so u have to draw a tree diagram to make sure it's correct

For the green it would be 6/10 and the red 2/10
