Find the probability if you pick two marbles without replacing the first. so we have 4 Green, 2 red and three yellow. What is the probability that the first roll is not red and what is the probability that the second roll is not red

4 + 2 + 3 = 9 total marbles

There are 2 red 

9 - 2 = 7

There is a 7/9 probability the first roll is not red.

I am confused what you mean by "picking two marbles without replacing the first." Please elaborate so I can answer the second part.
