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.

Essential Understandings
Concrete:
- Given a chance event, find the probability using a manipulative. For example, the probability of landing on yellow = 1/4 or 0.25.
- Understand the following concepts, symbols, and vocabulary for: probability and likelihood.
- Given a chance event, find the probability. For example the probability of rolling a 2 with a die is 1/6 or 0.166...
- Given a chance event, find the probability. For example the probability of rolling a B on a number die is 0/6 or 0.
- Given a chance event, find the probability. For example the probability of pulling a marble out of a bag of 5 marbles is 5/5 or 1.

Cluster:
Understand and evaluate random processes underlying statistical experiments. (Algebra 2 - Supporting Cluster) :
Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
