Suppose you have a box with 3 blue marbles, 2 red marbles, and 4 yellow marbles. You are going to pull out one marble, record its color, remove it from the box and draw another marble. What is the probability of pulling out a red marble followed by a blue marble? The multiplication rule says to use P (red) P (blue).

Describe the probability of finding a red marble?

Describe the probability of finding a blue marble?

Describe the process of finding the probability of finding a red marble followed by a blue marble if the first marble was permanently removed?

What affect did removing the first marble from the box have on the problem?
