The probability of pulling a red marble out of the bowl can be calculated by dividing the number of red marbles by the total number of marbles in the bowl.
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 = 120 - 108
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
Therefore, the probability that Nicole will pull 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. Use words and numbers to describe the probability that she will pull a red marble out of the bowl. Show your work.(4 points) pleaseeeee

alright big daddy i need it to look like a 7th grader answered it and not a robot
To find the probability of pulling a red marble, you have to remember that probability is just a fancy word for chance.
First, we need to figure out how many red marbles there are in the bowl. To do this, we need to subtract the number of black and white marbles from the total number of marbles.
Total number of marbles: 120
Number of black marbles: 80
Number of white marbles: 28
120 - 80 - 28 = 12 red marbles
Now, all we have to do is find the probability. That's just a way to show how likely something is to happen.
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
So, the probability that Nicole will pull a red marble out of the bowl is 0.1 or 10%.

could it be smaller perhaps but still not 1th grader answer?
Sure thing! Here's a simplified version:
To find the chance of picking a red marble, we first need to see how many red marbles are in the bowl. We can do this by subtracting the total number of black and white marbles from the total number of marbles.
Total marbles: 120
Black marbles: 80
White marbles: 28
120 - 80 - 28 = 12 red marbles
Now, we can find the probability:
Probability of getting a red marble = Number of red marbles / Total number of marbles
Probability of getting a red marble = 12 / 120
Probability of getting a red marble = 0.1 or 10%
So, the chance of Nicole pulling a red marble is 10%.
