The probability of pulling a red marble can be calculated by dividing the total number of red marbles by the total number of marbles in the bowl.

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

Therefore, the probability that Nicole pulls a red marble out of the bowl is 1/10 or 0.1.
