Alright, so there are 120 marbles total in the bowl. Of those, there are 80 black marbles, 28 white marbles, and some red marbles. We don't know how many red marbles there are, but we can figure out the probability of pulling a red one.
So, the probability of getting a red marble is the number of red marbles divided by the total number of marbles. That's like saying how many chances you have of getting a red one out of all the marbles.
We know there are 80 black marbles and 28 white marbles, so that leaves 120 - 80 - 28 = 12 red marbles.
The probability of pulling a red marble is 12 red marbles / 120 total marbles = 1/10.
So, there's a 1 in 10 chance that Nicole will pull a red marble out of the bowl. And that's how you figure it out, pretty cool right?
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. and make it sound like a 7th grade boy
