A marble is drawn at random from a bag that contains 3 green, 4 yellow, 5 blue, and 8 pink marbles. What is the probability that the marble drawn is green or blue?

OpenStudy (anonymous):

If you add all the marbles together it is 20

OpenStudy (anonymous):

So there are 3 green so the probability for that is 3/20

OpenStudy (anonymous):

thank you

OpenStudy (anonymous):

Blue is 5/20

OpenStudy (anonymous):

Add them together it is 8/20 reduce the fraction

OpenStudy (anonymous):

And it is 2/5
