To find the chance of Nicole picking a red marble, we have to count how many red marbles there are. First, we add up all the marbles: 80 black + 28 white + how many red = 120 total marbles. This means 108 marbles are either black or white. So subtract 108 from 120 to find out how many red marbles there are: 120 - 108 = 12 red marbles.
Now, to find the probability, we take the number of red marbles (12) and divide it by the total number of marbles (120). So, 12 ÷ 120 = 0.1. This means there is a 0.1 or 10% chance that Nicole will pull out a red marble from the bowl.
Now, to find the probability, we take the number of red marbles (12) and divide it by the total number of marbles (120). So, 12 ÷ 120 = 0.1. This means there is a 0.1 or 10% chance that Nicole will pull out a red marble from the bowl.

Step 1: Count the total number of marbles in the bowl: 80 black + 28 white = 108 marbles.
Step 2: Subtract the total number of marbles from the total number of marbles in the bowl to find out how many red marbles there are: 120 total marbles - 108 marbles = 12 red marbles.
Step 3: Calculate the probability of pulling a red marble by dividing the number of red marbles by the total number of marbles: 12 red marbles ÷ 120 total marbles = 0.1.
Step 4: Convert the probability to a percentage by multiplying by 100: 0.1 x 100 = 10%.
Therefore, there is a 10% chance that Nicole will pull a red marble out of the bowl.
Step 2: Subtract the total number of marbles from the total number of marbles in the bowl to find out how many red marbles there are: 120 total marbles - 108 marbles = 12 red marbles.

Step 4: Convert the probability to a percentage by multiplying by 100: 0.1 x 100 = 10%.
Therefore, there is a 10% chance that Nicole will pull a red marble out of the bowl.

Step 1: Add up the black and white marbles in the bowl to get the total: 80 black + 28 white = 108 marbles.
Step 2: Find the number of red marbles by subtracting the total from the total number in the bowl: 120 total marbles - 108 total marbles = 12 red marbles.
Step 3: Calculate the probability of picking a red marble by dividing the number of red marbles by the total number of marbles: 12 red marbles ÷ 120 total marbles = 0.1.
Step 4: Convert the probability to a percentage by multiplying by 100: 0.1 x 100 = 10%.
So, there is a 10% chance that Nicole will pick a red marble out of the bowl.
Step 2: Find the number of red marbles by subtracting the total from the total number in the bowl: 120 total marbles - 108 total marbles = 12 red marbles.
