Let $\displaystyle {A}={\left\lbrace{1},{3},{4},{6},{10},{14},{16},{19},{20}\right\rbrace}$ and $\displaystyle {B}={\left\lbrace{1},{2},{8},{9},{14},{16},{18},{20}\right\rbrace}$

Find the following:

LIST the elements in the set $\displaystyle {A}\cup{B}$:
$\displaystyle {A}\cup{B}$ = { }
Enter the elements as a list, separated by commas. If the result is the empty set, enter DNE

LIST the elements in the set $\displaystyle {A}\cap{B}$:
$\displaystyle {A}\cap{B}$ = { }
Enter the elements as a list, separated by commas. If the result is the empty set, enter DNE
