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.
Given that there are 80 black marbles, 28 white marbles, and a total of 120 marbles in the bowl, we can calculate the number of red marbles by subtracting the sum of black and white marbles from the total:
120 total marbles - 80 black marbles - 28 white marbles = 12 red marbles
Therefore, the probability of Nicole pulling a red marble is:
12 red marbles / 120 total marbles = 1/10 or 0.1, which is equivalent to a 10% chance.
