Students determine the sample space for a chance experiment.

Given a description of a chance experiment and an event, students identify the subset of outcomes from the sample space corresponding to the complement of an event.

Given a description of a chance experiment and two events, students identify the subset of outcomes from the sample space corresponding to the union or intersection of two events.

Students calculate the probability of events defined in terms of unions, intersections and complements for a simple chance experiment with equally likely outcomes.
