Answer 1

To find the probability that Nicole pulls a red marble out of the bowl, we first need to determine how many red marbles there are. There are 120 marbles total: 80 are black and 28 are white. We can find the number of red marbles by subtracting the black and white marbles from the total: 120 - 80 - 28 = 12 red marbles.

The probability of pulling a red marble can be calculated using the formula:

Probability = Number of favorable outcomes / Total number of outcomes.

In this case, the probability is 12 red marbles divided by 120 total marbles, which simplifies to 12/120 = 1/10. Therefore, the probability that Nicole will pull a red marble is 1/10, or 0.1, meaning there is a 10% chance she will pick a red marble.
