Use These Sets to Find the Following $\mathrm { U } = \{ 8,9,10,11,12,13,14,15,16,17,18 \} , \mathrm { M } = \{ 8,10,12,14 \} , \mathrm { N } = \{ 9,11,13,15,17 \}$

Multiple Choice

Use these sets to find the following. Identify any disjoint sets.
-Let $\mathrm { U } = \{ 8,9,10,11,12,13,14,15,16,17,18 \} , \mathrm { M } = \{ 8,10,12,14 \} , \mathrm { N } = \{ 9,11,13,15,17 \}$ , $Q = \{ 8,10,12,14,16,18 \}$ , and $R = \{ 8,9,10,11 \}$ .

$\varnothing \cup \mathrm { N }$

A) $\{ 8,9,10,11,12,13,14,15,16,17,18 \}$
B) $\mathrm { N }$ , or $\{ 9,11,13,15,17 \}$ ; $\mathrm { N }$ and $\varnothing$ are disjoint sets.
C) $\{ 10,12,14,16,18 \}$
D) $\varnothing ; N$ and $\varnothing$ are disjoint sets.
