Question

Nicole pulls a colored marble out of a bowl, choosing the marble at random. There are 120 marbles in the bowl, of which 80 are black, 28 are white, and the rest are red. Use words and numbers to describe the probability that she will pull a red marble out of the bowl. Show your work.

Number of red marbles = 120 - (80 + 28)
Number of red marbles = 120 - 108
Number of red marbles = 12
so then that means that there are 12 marbles in a bowl

To calculate the probability of pulling a red marble out of the bowl, we need to divide the number of red marbles by the total number of marbles in the bowl.

Probability of choosing a red marble = Number of red marbles / Total number of marbles
Probability of choosing a red marble = 12 / 120
Probability of choosing a red marble = 1/10
Therefore, the probability that Nicole will pull a red marble out of the bowl is 1/10.
