Learning Goal
Part of: Investigate chance processes and develop, use, and evaluate probability models — 1 of 4 cluster items
Understand that the probability of a chance event is a number between 0 and 1
7.SP.C.5 -- Understand that the probability of a chance event is a number between 0 and 1 that expresses the likelihood of the event occurring. Larger numbers indicate greater likelihood. A probability near 0 indicates an unlikely event, a probability around 1/2 indicates an event that is neither unlikely nor likely, and a probability near 1 indicates a likely event.

What you'll learn
- Define probability as a measure of how likely an event is to occur
- Express probability as a number between 0 and 1 (or 0% and 100%)
- Interpret probability values: 0 = impossible, near 0 = unlikely, 1/2 = equally likely and unlikely, near 1 = likely, 1 = certain
- Place events on a probability number line according to their estimated likelihood
- Distinguish between impossible, unlikely, equally likely/unlikely, likely, and certain events
- Explain why a probability cannot be less than 0 or greater than 1
