The probability of pulling a red marble out of the bowl can be found by dividing the number of red marbles by the total number of marbles.
Number of red marbles = 120 - (80 + 28)
Number of red marbles = 12
Total number of marbles = 120
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 will pull a red marble out of the bowl is 1 out of 10.
