#### Understanding

Students will recognize that the probability of an outcome can be estimated from the long-run relative frequencies.

### What to look for

Students should notice that the more repetitions of an experiment leads to an relative frequency that is closer to the theoretical probability.### Sample Assessment

Identify each as true or false:

a. The probability of an outcome can be 2/1.

b. The probability of an outcome can be 0.

c. If an outcome is sure to happen, the probability of the outcome is 1.

Responses:

a. False

b. True

c. True
