Mary Katherine has a bag of 3 red apples, 5 yellow apples and 4 green apples. Mary takes a red apple out of the bag and does not replace it. What is the probability that the next apple she takes out is yellow?
Since Mary Katherine takes a red apple out of the bag, there are 11 apples left. Five of those apples are yellow. So the probability of taking a yellow apple out of the bag is 5/11.
