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. In two to four sentences , use words and numbers to describe the probability that she will pull a red marble out of the bowl. Show your work. and make your answer simple
The probability of Nicole 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. There are 80 black marbles, 28 white marbles, so there must be 12 red marbles (since 120 - 80 - 28 = 12). Therefore, the probability of pulling a red marble is 12/120, which reduces to 1/10 or 0.1. This means that there is a 10% chance that Nicole will pull a red marble out of the bowl.
