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?
The solution is 5/11
<em>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</em>
This is because there were originally 12 apples and because she did not replace the apple she took out, she has a higher probability of getting a yellow apple</span><span />
