There is an equal amount of yellow, blue, green, and red marbles in a bag of 24 marbles. If Ed draws 12 marbles out of the bag with replacement, predict how many of the 12 marbles drawn should be green.

Since there are 6 green marbles in the bag and a total of 24 marbles, the probability of drawing a green marble is 6/24 = 1/4.
If Ed draws 12 marbles with replacement, the expected value of drawing green marbles would be 12 * (1/4) = 3.
Therefore, it is predicted that 3 of the 12 marbles drawn should be green.
