Nicole pulls a colored marble out of a bowl, choosing the marble at random. There are 120 marbles in the bowl, of which 80

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 = Total number of marbles - (Number of black marbles + Number of white marbles)
Number of red marbles = 120 - (80 + 28)
Number of red marbles = 120 - 108
Number of red marbles = 12

So, the 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 = 0.1 or 10%

Therefore, there is a 10% chance that Nicole will pull a red marble out of the bowl.
