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 pulling a red marble out of the bowl is the number of red marbles divided by the total number of marbles in the bowl.

Number of red marbles = 120 (total number of marbles) - 80 (black marbles) - 28 (white marbles) = 12 red marbles

Probability of pulling a red marble = 12 (number of red marbles) / 120 (total number of marbles) = 1/10

So, the probability that Nicole will pull a red marble out of the bowl is 1/10.
