Suppose Susan chooses one marble out of the bag, replaces it, and then chooses a second
marble out of the bag. The probability she would choose a red marble and then a green
marble is
or 3%. You multiply the probability of choosing each color together and
the product is the probability she will choose both colors. Use this to find each probability
below assuming she chooses one marble, replaces it, and then chooses a second marble. Write
as a fraction, decimal and percent.
