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, 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. Like a 7th grader wrote it

Answer 1

The probability of 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.

Number of red marbles = 120 - 80 - 28 = 12
Total number of marbles = 120

So, probability = Number of red marbles / Total number of marbles
= 12 / 120
= 1 / 10

Therefore, the probability of Nicole pulling a red marble out of the bowl is 1/10 or 0.1.
