Exercise 28 Page 289

Start by calculating the number of non-green parts on the spinner.

Is Statement True or False? False
Correct Statement: Spinning not green can occur in eight ways on Spinner B.

Practice makes perfect

We want to determine whether the given statement is true or false.

Spinning not green can occur in three ways on Spinner B.

Let's start by looking at the given spinner!
Notice that there are 10 parts on the spinner colored red, green, blue, and yellow. In this case, we can determine in how many way we can spin not green by calculating the number of parts colored red, blue, or yellow on the spinner. Let's do it!
Out of all parts on the spinner, 8 parts are not green. This means that we can spin not green in eight ways. We can use this information to correct the given statement.

Spinning not green can occur in eight ways on Spinner B.
