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 and unlikely event, a probability around 1/2 indicates an event that neither unlikely nor likely, and a probability near 1 indicates a likely event.

7.SP.5 -Black & White -http://insidemathematics.org/index.php/tools-for-teachers/6th-grade-math/mars-tasks-scoring-rubrics-a-analysis - The Black & White task listed on this page requires a knowledge of fractions and simple probability. These tasks also have sample student work, teacher reflections, and other resources.My Humble OpinionThis has moved up from 4th grade, so students should have seen this before. This is rather intuitive and easy to teach.
