A bag contains 7 red marbles, 2 blue marbles, and 1 green marble. If a marble is selected at random, what is the probability of choosing a marble that is not blue?

I have seen so many different answers on this site to this question and am not sure. I thought it would be 7 red +1 green gives 8/10=4/5.

Our choices for the answer is 4/5,1/5, 5/4, 8

    Right! 4/5 it is!
