If \( \Large A=\{ 1, 2, 3, 4 \},\ B=\{ 3, 4, 5, 6 \},\ C=\{ 6, 7, 8, 9 \} \) then find the set \( \Large A\cap \left(B\cup C\right) \)


A) \( \Large \{ 1, 2 \} \)

B) \( \Large \{ 2, 3 \} \)

C) \( \Large \{ 3, 4 \} \)

D) \( \Large \{ 6, 7 \} \)

Correct Answer:
C) \( \Large \{ 3, 4 \} \)

Description for Correct answer:
\( \Large A=\{ 1,2,3,4 \},\ B=\{ 3,4,5,6 \},\ C=\{6,7,8,9 \} \)

\( \Large B\cup C = \{ 3,4,5,6,7,8,9 \} \)

\( \Large A\cap \left(B\cup C\right) = \{ 3,4 \} \)
