The total number of marbles in the bowl is 120. Out of these, 80 are blue and 28 are white, so the number of red marbles is:

120 - 80 - 28 = 12 red marbles

Therefore, the probability of pulling a red marble out of the bowl is:

12 red marbles / 120 total marbles = 1/10 = 0.10 = 10% probability

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