Question

The _____ of an event E is the set of all outcomes in the sample space S that are not outcomes in the event E.

Short answer

complement

Step-by-step solution

Step 1. Given information.

The _____ of an event $E$is the set of all outcomes in the sample space $S$that are not outcomes in the event $E$.

Step 2. Fill up the blank. 

The complement of an event $E$is the set of all outcomes in the sample space $S$that are not outcomes in the event $E$.

Just like the complement of a set, in events if the set contains all the outcomes on sample space $S$that are not in the outcomes in event $E$, we call it the complement of an event $E$.
