Nicole pulls out a colored marble out of a bowl 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

Answer 1

The total number of marbles in the bowl is 120.

The number of red marbles in the bowl is the remaining marbles after subtracting the black and white marbles:
120 - 80 - 28 = 12

Therefore, the probability of Nicole pulling a red marble out of the bowl is:
Number of red marbles / Total number of marbles = 12/120 = 1/10

So, the probability is 1/10 or 0.1.
