## Lesson 11.3 Spinners and Probability

Open the Online Spinner website above and move it to the side for now.

Use

On the spinner page, use the up and down arrows to change the number of sections. Put your cursor into the section you want to change colors, then click the color on the right. Click apply to check your spinner.

Make a spinner that has 8 sections altogether.

Make 6 of them (3/4) red, and 2 of them (2/8) blue.

Mark the spinner on the Math Master page to match.

Click the button that says "Record Results" and a white box will pop up. Type in the number 10 and click Spin

On a piece of paper, record how many times the spinner landed on blue or red.

Example: #1: red 6, blue 4

Spin another time (really another 10 spins) and record these results.

Example: #1: red 6, blue 4

red 11, blue 9

Clear the results by hitting the Clear button.

Change the number of spins to 100 and click Spin again. Record your results.

Example: #1: red 6, blue 4 = 10

red 11, blue 9 = 20

red 79, blue 21= 100

Now, clear the results, and click on Change Spinner for

This time, you will need 6 sections: 1 (or 1/6) blue, 2 (or 1/3) yellow, and 6 (or 1/2) red.

Do the same thing again- spin 10 times, another 10 times, then 100 times. Record your results.
