Answer 1

The correct choice is:

C. No. The spinner is not fair because there are more white sections than yellow sections. A fair spinner will have
5 yellow sections and 5 white sections.

To make it a fair spinner, you would need to adjust the number of sections so that the yellow and white sections are equal, resulting in a balanced probability of landing on either color. In this case, that would mean having 5 yellow sections and 5 white sections.
