Abag has 8 red marbles, 4 green marbles, and 2 yellow marbles. bill draws a red marble from the bag and does not replace it. what is the probability of bill drawing a yellow marble next?

So there is a total of 14 marbles and when Bill takes one red out it becomes 13 marbles. So the probability of Bill drawing a yellow marble is 2 yellow marbles (because there are 2 yellow) out of 13. So the answer is the probability is 2/13 of drawing yellow!
