5 green marbles and 4 yellow marbles in a bag. 4 p red 2 p purple 3 p black 1 you draw a marble out of the bag and then replace it. So what we do is figure out the probability of pulling out a blue marble and then the probability of pulling out another after not replacing the first. A draw the tree diagram for the experiment.

If we got a red marble before then the chance of a blue marble next is 2 in 4. So they say the probability i ll just say p for probability. Find the probability of pulling a yellow marble from a bag with 3 yellow 2 red 2 green and 1 blue i m assuming marbles. A red marble first and a blue marble second.

Find the probability of the first marble being green and the second marble being yellow. We will call these event 1 and 2.
