One last question- Nicole pulls a colored marble out of a bowl, choosing the marble at random. There are 120 marbles in the bowl, of which 80 are black, 28 are white, and the rest are red. Use words and numbers to describe the probability that she will pull a red marble out of the bowl. Show your work.

The probability of Nicole pulling a red marble out of the bowl can be calculated by dividing the number of red marbles by the total number of marbles in the bowl.
Number of red marbles = 120 (total marbles) - 80 (black marbles) - 28 (white marbles) = 12 red marbles.
Probability = 12 (number of red marbles) / 120 (total number of marbles) = 1/10 or 0.1 or 10%.
Therefore, the probability that Nicole will pull a red marble out of the bowl is 10%.
