To find the probability of pulling a red marble, we need to first figure out how many red marbles there are in the bowl.

We know that there are 80 black marbles, 28 white marbles, and 120 marbles in total. If we subtract the number of black and white marbles from the total, we can find out how many red marbles there are:

120 total marbles - 80 black marbles - 28 white marbles = 12 red marbles

So, there are 12 red marbles in the bowl.

Now, to find the probability of pulling a red marble, you need to divide the number of red marbles by the total number of marbles:

12 red marbles / 120 total marbles = 1/10

This means that the probability of Nicole pulling a red marble out of the bowl is 1 out of 10.
