7-116.

Jessica wants to make a spinner that has all of the following characteristics. Sketch a possible spinner for Jessica. Be sure to label each section of the spinner with a name and with its theoretical probability.

• Blue, red, purple, and green are the only colors on the spinner.

• It is half as likely to land on blue as to land on red.

• It is three times as likely to land on purple as green.

• There is a $50\%$ probability of landing on either blue or red and a $50\%$ probability of landing on either purple or green.

You know from characteristics $1$ and $4$ that $\text{blue}+\text{red}$ and $\text{purple}+\text{green}$ each equal one-half as shown below.

Use the eTool below to create the spinner with the characteristics outlined in the problem.
