#### Understanding

Students recognize the difference between outcomes of a chance event that are equally likely and those that are not.

### What to look for

By the end of this lesson, students should be able to use their experimental results and the theoretical probabilities to explain why the events in a chance process are or are not equally likely.### Sample Assessment

Are the outcomes in the spinner equally likely? Why or why not?

Answer:

No, because the probability of getting each color is not the same: the probability of getting a red is (3/6), blue is (2/6) and green is (1/6).
