a. Draw a model that you can use to determine the number of marbles that will be pink in a multi-colored package of 21 marbles.

Answer 1

The number of marbles that will be pink in a multi-colored package of 21 marbles is 14

How to determine the number of marbles that will be pink

From the question, we have the following parameters that can be used in our computation:

Pink = Two out of every three marbles

This means that the proportion of pink is

Pink = 2/3

Also, we have

Marbles = 21

Using the above as a guide, we have the following:

Pink = 2/3 * 21

Evaluate

Pink = 14

Hence, the number of marbles that will be pink is 14
