Rita's friend Pamilla models Rita's experiment by drawing a spinner with three equal sections labeled
1, 2, and 3.
Is the spinner Pamilla drew a good model for Rita's experiment? Why or why not?

Responses
Yes, all spinners should have equal sections.
.
Yes, there are three numbers and three sections.

No, the three events are not equally likely to occur.

No, the spinner should have more than three sections.

1 answer

The correct response is:

No, the three events are not equally likely to occur.

Rita's experiment showed that the frequency of landing on each number was not equal: 10 times for 1, 35 times for 2, and 55 times for 3. This indicates that the likelihood of landing on each number is different, while Pamilla's spinner is designed with three equal sections, implying that each number (1, 2, or 3) has an equal chance of being selected. Therefore, Pamilla's spinner does not accurately model the results of Rita's experiment.
