Question

yo bot,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.(4 points)

Answer 1

The total number of marbles in the bowl is 120.

The number of red marbles in the bowl is the difference between the total number of marbles and the sum of the number of black marbles and the number of white marbles:
120 - (80 + 28) = 12

Therefore, there are 12 red marbles in the bowl.

The probability that Nicole will pull a red marble out of the bowl can be calculated by dividing the number of red marbles by the total number of marbles:
12/120 = 1/10 = 0.1

So, the probability that she will pull a red marble out of the bowl is 0.1 or 10%.

Answer 2

which one is it 120 or 1/10

Answer 3

I apologize for the confusion. The correct probability that Nicole will pull a red marble out of the bowl is 1/10 or 0.1, which is equivalent to 10%.

Answer 4

do it setp by setp

Answer 5

Sure, here are the steps:

1. Determine the total number of marbles in the bowl, which is 120.

2. Calculate the number of red marbles in the bowl by subtracting the sum of black and white marbles from the total number of marbles:
Number of red marbles = Total number of marbles - (Number of black marbles + Number of white marbles)
Number of red marbles = 120 - (80 + 28)
Number of red marbles = 12

3. Calculate the probability of pulling a red marble by dividing the number of red marbles by the total number of marbles:
Probability of pulling a red marble = Number of red marbles / Total number of marbles
Probability of pulling a red marble = 12 / 120
Probability of pulling a red marble = 1/10
Probability of pulling a red marble = 0.1 or 10%

Therefore, the probability that Nicole will pull a red marble out of the bowl is 1/10 or 0.1, which is equivalent to 10%.
