Final answer:
To find the percentage of blue marbles, divide the number of blue marbles by the total and multiply by 100. In the given scenario, with four blue marbles and three white marbles, approximately 57.14% of the marbles are blue.
Step-by-step explanation:
To determine what percentage of the marbles are blue, we need to look at the ratio of blue marbles to the total number of marbles. In one scenario provided, a bag contains four blue and three white marbles. Therefore, the percentage of blue marbles is calculated by dividing the number of blue marbles by the total number of marbles and then multiplying by 100 to get the percentage.
Percentage of blue marbles = (Number of blue marbles / Total number of marbles) × 100
Percentage of blue marbles = (4 / (4 + 3)) × 100
Percentage of blue marbles = (4 / 7) × 100
Percentage of blue marbles = 57.14%
Thus, approximately 57.14% of the marbles are blue in this scenario. When looking at questions related to probability, such as the likelihood of drawing a blue marble or setting aside a marble, it's important to recalculate the percentages or probabilities based on the new composition of marbles remaining in the bag.
