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) make it short
The probability of Nicole pulling a red marble out of the bowl can be calculated by first determining how many red marbles are in the bowl. Since there are 80 black marbles and 28 white marbles, there are 120 - 80 - 28 = 12 red marbles in the bowl.
Therefore, the probability of pulling a red marble is 12 red marbles / 120 total marbles = 1/10 or 0.1. So, the probability of Nicole pulling a red marble is 0.1.
