There are 120 marbles in the bowl. 80 are black, 28 are white, and the rest are red. So, that means 80 + 28 = 108 marbles are either black or white. That leaves 120 - 108 = 12 marbles that are red in the bowl.

To find the probability of pulling a red marble, we need to divide the number of red marbles by the total number of marbles. So, the probability is 12 red marbles / 120 total marbles = 1/10 or 0.1.

So, Nicole has a 1 out of 10 chance of pulling a red marble out of the bowl.
