The total number of marbles in the bowl is 120.
The probability of pulling a black marble is given by:
Number of black marbles / Total number of marbles
= 80 / 120
= 2 / 3
= 0.67 (rounded to 2 decimal places)
The probability of pulling a white marble is given by:
Number of white marbles / Total number of marbles
= 28 / 120
= 7 / 30
= 0.23 (rounded to 2 decimal places)
The probability of pulling a red marble is:
Number of red marbles / Total number of marbles
= 12 / 120
= 1 / 10
= 0.1
Therefore, the probability of Nicole pulling a black marble is 0.67, the probability of pulling a white marble is 0.23, and the probability of pulling a red marble is 0.1.
