About this worksheet

What students practice

  • Students interpret probabilities from 0 to 1 as measures of an event's likelihood.
  • Students compare probabilities with 0, 1/2, and 1 to classify and rank events.
  • Students explain why a high probability does not guarantee an outcome.

How to use

Use after introducing the probability scale. Have students work independently, then discuss why a forecast and a posted result can differ.

Curriculum

Common Core standard covered

7.SP.C.5

Track Meet: Read the Chance Board

Interpret probabilities before comparing them with posted results.

Read the Chance Scale

Probabilities range from 0 to 1, including both endpoints. Interpret each track meet message.

1.
Before the meet, a forecast board gives a probability of 0.82 that the meet will finish before 5 p.m. Which description fits?
  • A. Finishing before 5 p.m. is unlikely.
  • B. Finishing before 5 p.m. is impossible.
  • C. Finishing before 5 p.m. is likely.
  • D. Finishing before 5 p.m. is certain.
2.
The completed results board lists six finalists in a race. Every finalist's time is less than 20 seconds. One finalist's name is selected at random.

What is the probability that the selected finalist's time is less than 20 seconds?  

3.
The completed results board lists only seventh- and eighth-grade competitors. One listed competitor is selected at random.

What is the probability that the selected competitor is in sixth grade?
