The probability of 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.
Number of red marbles = 120 - 80 - 28 = 12
Total number of marbles = 120
Probability = Number of red marbles / Total number of marbles
Probability = 12 / 120
Probability = 0.1 or 10%
Therefore, the probability that Nicole will pull a red marble out of the bowl is 10%.
