To find the probability of Nicole pulling a red marble out of the bowl, we first need to determine how many red marbles there are. We know that there are a total of 120 marbles in the bowl, with 80 black marbles, 28 white marbles, and some number of red marbles.
To find the number of red marbles, we'll subtract the number of black and white marbles from the total number of marbles:
120 total marbles - 80 black marbles - 28 white marbles = 12 red marbles
Now that we know there are 12 red marbles in the bowl, we can find the probability of Nicole pulling a red marble:
Probability = Number of favorable outcomes / Total number of outcomes
Probability = 12 red marbles / 120 total marbles
Probability = 1/10
Probability = 0.1
Therefore, the probability of Nicole pulling a red marble out of the bowl is 0.1 or 10%.
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.

Make it MUCH shorter while still showing your work.
Number of red marbles = Total 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 marbles
Probability of pulling a red marble = 12 / 120
Probability of pulling a red marble = 1/10
Probability of pulling a red marble = 0.1 or 10%
Number of red marbles = 120 - 80 - 28
Number of red marbles = 12
Probability of pulling a red marble = Number of red marbles / Total marbles
Probability of pulling a red marble = 12 / 120
Probability of pulling a red marble = 1/10
Probability of pulling a red marble = 0.1 or 10%
Put the equation into a sentence or two.
The probability of Nicole pulling a red marble out of the bowl is 1/10, or 0.1, which is equivalent to 10%.
Make it longer by a little bit.
To calculate the probability of Nicole selecting a red marble from the bowl, we first determine the number of red marbles by subtracting the total number of black and white marbles from the total number of marbles. With 80 black marbles, 28 white marbles, and 120 marbles in total, we find that there are 12 red marbles in the bowl. By dividing the number of red marbles by the total number of marbles, we arrive at a probability of 1/10, which is equivalent to 0.1 or 10%. Therefore, Nicole has a 10% chance of pulling a red marble from the bowl when selecting at random.
I said a little bit.
To determine the probability of Nicole selecting a red marble from the bowl, we begin by calculating the number of red marbles. By subtracting the 80 black marbles and 28 white marbles from the total of 120 marbles, we find that there are 12 red marbles in the bowl. Dividing the number of red marbles by the total number of marbles reveals a probability of 1/10, which can be expressed as 0.1 or 10%. Therefore, there is a 10% chance that Nicole will choose a red marble when randomly selecting from the bowl.
Make it shorter.
To find the probability of Nicole picking a red marble, we subtract the number of black and white marbles (80 and 28, respectively) from the total number of marbles (120) to get 12 red marbles. Dividing the number of red marbles by the total marbles gives a probability of 1/10 or 0.1, equivalent to 10%. Therefore, Nicole has a 10% chance of selecting a red marble from the bowl randomly.
