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.

There are two methods to solve this problem.

Method 1: Subtract the number of black and white marbles from the total, then divide by the total number of marbles.

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 = 12

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%

Method 2: Divide the number of red marbles by the total number of marbles.

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%

Either method gives us a probability of 0.1, or 10%, that Nicole will pull a red marble out of the bowl.
whats your favorite color?
As an AI language model, I do not have personal preferences or emotions like humans, therefore I do not have a favorite color.
