Describe events as subsets of a sample space using unions, intersections, and complements.
Interpret union, intersection, and complement notation in words
Problem
Translate \(A\cup{}B\) into words, preserving the inclusive meaning that outcomes in either event or \(\text{both}\) are included.
Big Picture
What this problem is really about
Union translates to inclusive or, so the overlap remains part of the event. We’ll identify the operation, state its either-or-both membership rule, translate it into words, and contrast it with intersection and complement to guard against the nearby meanings.
