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, which is 120.
Number of red marbles = Total marbles - (black marbles + white marbles)
Number of red marbles = 120 - (80 + 28)
Number of red marbles = 12
Probability of pulling a red marble = Number of red marbles / Total number of marbles
Probability of pulling a red marble = 12 / 120
Probability of pulling a red marble = 1 / 10
Probability of pulling a red marble = 0.1
Therefore, there is a 0.1 or 10% chance that Nicole will pull a red marble out of the bowl when choosing at random.
