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, put it back in 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). Using this information and the answer the questions below: 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.
What effect did putting the first marble back in the box have on the problem?
Describe the probability of finding a red marble followed by the blue marble. Explain why this is the case.
