Use These Sets to Find the Following $\mathrm { U } = \{ 9,10,11,12,13,14,15,16,17,18,19 \} , \mathrm { M } = \{ 9,11,13,15 \} , \mathrm { N } = \{ 10,12,14,16,18 \}$

Multiple Choice

Use these sets to find the following. Identify any disjoint sets.
-Let $\mathrm { U } = \{ 9,10,11,12,13,14,15,16,17,18,19 \} , \mathrm { M } = \{ 9,11,13,15 \} , \mathrm { N } = \{ 10,12,14,16,18 \}$ , $Q = \{ 9,11,13,15,17,19 \}$ , and $R = \{ 9,10,11,12 \}$ .
$\mathrm { M } \cup \mathrm { N }$

A) $\{ 9,10,11,12,13,14,18 \}$
B) $\varnothing ; \mathrm { M }$ and $\mathrm { N }$ are disjoint sets.
C) $\{ 9,10,11,12,13,14,15,16,18 \}$
D) $\{ 10,11,12,13,14,15,16,17,18 \}$
