Let S\displaystyle {S} be the universal set, where:
S={1,2,3,,8,9,10}\displaystyle {S}={\left\lbrace{1},{2},{3},\ldots,{8},{9},{10}\right\rbrace}
Let sets A\displaystyle {A} and B\displaystyle {B} be subsets of S\displaystyle {S}, where:

Set A={1,3,8,9,10}\displaystyle {A}={\left\lbrace{1},{3},{8},{9},{10}\right\rbrace}

Set B={1,1,4,6,8,9}\displaystyle {B}={\left\lbrace{1},{1},{4},{6},{8},{9}\right\rbrace}

Write out the following sets in roster notation and state the cardinality of the sets.


AB={\displaystyle {A}\cup{B}={\lbrace} }\displaystyle {\rbrace}


n(AB)=\displaystyle {n}{\left({A}\cup{B}\right)}=


AB={\displaystyle {A}\cap{B}={\lbrace} }\displaystyle {\rbrace}


n(AB)=\displaystyle {n}{\left({A}\cap{B}\right)}=


A={\displaystyle {A}'={\lbrace} }\displaystyle {\rbrace}


n(A)=\displaystyle {n}{\left({A}'\right)}=


B={\displaystyle {B}'={\lbrace} }\displaystyle {\rbrace}


n(B)=\displaystyle {n}{\left({B}'\right)}=
