a bag has 2 yellow marbles, 5 red marbles and 3 green marbles. What is the probability of drawing a red and yellow marble in any order without replacement?

OpenStudy (anonymous):

Ok, so we have 10 marbles in all. And added together, Red and yellow is 7 marbles. There you go! Would you like a fraction, or percent? :D

OpenStudy (anonymous):

I did 2/10 for yellow times 5/10 for red and got a probability of 0.1

OpenStudy (anonymous):

They want both Red AND yellow, not separate.
