Question
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)
To find the probability of Nicole pulling a red marble out of the bowl, we need to first determine how many red marbles are in the bowl.
There are a total of 120 marbles in the bowl.
Of these, 80 are black, 28 are white, which means that there are (120 - 80 - 28) = 12 red marbles in the bowl.
Therefore, the probability of Nicole pulling a red marble is:
(number of red marbles) / (total number of marbles) = 12 / 120 = 1 / 10 = 0.1
So, the probability is 0.1 or 10%.

So like, Nicole is pulling a marble out of a bowl filled with 120 marbles. There are 80 black marbles, 28 white marbles, and some red marbles in there. We need to find out the chance of her getting a red marble.
So, there are 12 red marbles in the bowl out of 120 marbles in total. To find the probability, it's like this: 12 red marbles out of 120 marbles. So, the probability is like 12 out of 120 which simplifies to 1 out of 10 or 0.1 in decimal. So, the chance of Nicole getting a red marble is like 10%.
