Question

The bar chart shows the percent of times each color marble was drawn from a bag after 1000 draws with replacement after each draw. If there are 20 marbles in the bag, predict how many are red, how many are blue, and how many are white. Explain your reasoning.

Answer 1

Following are the solution to this question:

Explanation:

In this question, the graph file is missing so, its solution can be defined as follows:

When the bag includes 20 marbles, each will be drawn 5% of the time on average.

The bar chart shows that nearly 50% of the workforce red marbles are drawn, and about 25% of the time blue and white marbles are drawn. so, the equation is:

`\to (50\%)/(5\%)= (50 * 100)/(5* 100)=(50)/(5) = 10 \ red \ marbles\\\\\to (25\%)/(5\%)= (25 * 100)/(5* 100)=(25)/(5) = 5\ blue \ marbles`

`\to 5` white marbles are available in the bag.
