Answer 2

Answer:

Step-by-step explanation:

$\underline\bold{Given \colon} \\ A = \{{1,2,3,4} \},B = \{3,4,5,6 \} \\ and \: C = \{1,2,4,6,7 \} \\ \underline \bold{ To \: find \colon} \\ (A - B)U(A-C) \\ \underline \bold{Solution \colon} \\(A-B)=\{{1,2,3,4}\}-\{3,4,5,6\} \\ = \{1,2 \} \\ (A - C) =\{{1,2,3,4}\}- \{1,2,4,6,7 \} \\ = \{ 3\} \\ (A-B)U(A-C) =\{1,2 \}U\{ 3\} \\ \purple{\fbox{ \red{(A-B)U(A-C) = \{1,2,3\}}}}$
