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. But write it fairly simple as if you were a 7th/8th grader. And for anyone copying this, use your own words for you'll be plagarizing

To find the probability of pulling a red marble, we first need to figure out how many red marbles there are. We know that there are 80 black marbles and 28 white marbles, which means there are 80 + 28 = 108 marbles that are not red.

Since there are a total of 120 marbles in the bowl, we can subtract the non-red marbles from the total to find out how many red marbles there are. 120 - 108 = 12 red marbles.

Now we can find the probability of pulling a red marble by dividing the number of red marbles by the total number of marbles. So, the probability is 12 red marbles / 120 total marbles = 1/10 or 10%. This means there is a 10% chance that Nicole will pull a red marble from the bowl.
No bot, much more short
The probability of pulling a red marble is 1/10 or 10%.
But still show your work
There are a total of 120 marbles in the bowl.

Number of non-red marbles = 80 black + 28 white = 108.

Number of red marbles = 120 total marbles - 108 non-red marbles = 12 red marbles.

Probability of pulling a red marble = Number of red marbles / Total number of marbles = 12 / 120 = 1/10 = 10%.
