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. Write like a 7th grader
The probability that Nicole will pull a red marble out of the bowl is 12/120, which simplifies to 1/10. This means that out of every 10 marbles she could choose, one of them will be red.
To find this probability, I divided the number of red marbles (10) by the total number of marbles in the bowl (120) because that's the definition of probability - the chances of an event happening divided by all possible outcomes. So, the probability of Nicole pulling a red marble is 1/10.
