About this worksheet

What students practice

  • Students interpret probabilities using impossible, equally likely, and certain benchmarks.
  • Students compare probabilities and use likelihood to evaluate gym decisions.
  • Students distinguish equal probabilities from events having identical outcomes.

How to use

Use after introducing the probability scale from 0 to 1. Have students work independently, then discuss how probability differs from a guarantee.

Curriculum

Common Core standard covered
