Sample Space
Definition 1. Sample space is the set of all possible outcomes of an experiment, and is usually denoted by $S$.
모든 시행에서 나올 수 있는 결과값을 모아놓은 집합을 sample space, 표본 공간이라고 부른다.
Event
Definition 2. Any subset $E$ of the sample space is called an event. In other words, an event is a set consisting of possible outcomes of the experiment. If the outcome of the experiment is contained in $E$, then we say that $E$ has occurred.
Sample space의 부분 공간을 event, 사건이라고 부른다. 다시 말해 결과값들을 일부 모아놓은 집합을 의미한다.
