The table shows the results of drawing one marble from a bag of colored marbles. Each marble was replaced after the outcome was recorded. If there are a total of 50 marbles in the bag, about how many of the marbles are black?
A.15
B.6
C.12
D.9
No table. You cannot copy and paste here.
To find out how many black marbles are in the bag, we can look at the results of drawing marbles and use that information to estimate the number of black marbles. However, since the table showing the results is not provided, we need more information.
If the table is provided with the number of times each color was drawn, we can calculate the estimated number of black marbles by following these steps:
1. Add up the number of times each color was drawn.
2. Divide the number of times black was drawn by the total number of marbles drawn.
3. Multiply the result by the total number of marbles in the bag.
For example, if the table showed that black was drawn 3 times and a total of 20 marbles were drawn, we would calculate as follows:
1. The number of times black was drawn = 3.
2. The total number of marbles drawn = 20.
3. The estimated number of black marbles = (3/20) * 50 = 7.5
Based on this calculation, we can estimate that there are approximately 7 or 8 black marbles in the bag.
Without the table or any other information, it is not possible to determine the exact number of black marbles. Therefore, we cannot provide a definitive answer among the options given (A. 15, B. 6, C. 12, D. 9).
