Question

A jar contains 5 red marbles and 3 green marbles.  A marble is drawn at random and not replaced.  A second marble is then drawn from the jar. Find the probability that both marbles are the same color.

I figured out that the probability that both marbles are red is 20/56 and the probability that both are green is 6/56. Then I added them together to get 26/56.  Is this correct? Thanks!

yes, good job however, you should reduce 26/56 to 13/28
