Def. 
For each outcome $\zeta\in S,$ (ζ: [[결과,outcome]], S: [[표본공간,sample_space]])
consider function $X:\zeta\mapsto X(t,\zeta),\quad t\in I$

먼저 결과를(outcome을) 픽스.
then, for fixed $\zeta,$ the graph[* 이 그래프는 이름이 여러가지임. sample path(표본경로), sample function(표본함수), realization of random process(확률 과정의 실현)] of function $X(t,\zeta):$

다음은 시간을 픽스.
and for fixed $t=t_k,\;X(t_k,\forall\zeta)=X_k$ : random variable

then, $\lbrace X(t,\forall\zeta\in S),t\in I\rbrace\equiv X(t),\quad t\in I$
