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) can you answer this and make it kind of short and make it sound like a 7th grader?

Sure! The probability of Nicole pulling a red marble out of the bowl is the number of red marbles divided by the total number of marbles. In this case, there are a total of 120 marbles in the bowl and the number of red marbles is not given, but we know it is less than 80 (because there are 80 black marbles). So, the probability of pulling a red marble is less than 1/2 (because there are more black marbles than red marbles).
what is the exact probability though
We know that there are 80 black marbles and 28 white marbles, which together make 108 marbles. So, the remaining marbles must be red, which is 120 - 108 = 12 red marbles. Therefore, the probability of Nicole pulling a red marble out of the bowl is 12/120 = 1/10 = 0.1 or 10%.
so can you rewrite that with the answer in it please?
Sure! The exact probability of Nicole pulling a red marble out of the bowl is 1/10, which is equivalent to 0.1 or 10%.
write what you wrote the first plus the answer
Sure! The probability of Nicole pulling a red marble out of the bowl is less than 1/2 because there are more black marbles than red marbles. After calculating, we found that the exact probability is 1/10, which is equivalent to 0.1 or 10%.
