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.
