    Hello, Adina!

    Use a Venn diagram to represent: . S \;=\;A \cup B\cup C\:\!^c
    Consider the complement of S.

    S^c \;=\:(A \cup B \cup C^c)^c  \;= \;A^c \cap B^c \cap C . . . by DeMorgan's Law

    \text{So, }S\text{-complenent has the elements that are: }\:\begin{Bmatrix}\text{not in }A, \\<br />
\text{not in }B, \\<br />
\text{and in }C. \end{Bmatrix}

    This is the region that is in C only.
    . . Visualize that region.

    Then S is everthing but that region.
