Question

If A = {3, 5}, B = {2, 3, 4} and C = {4, 5}, find then A $\cap$ (B $\cup$ C).

• A. {1, 2, 3, 4, 5, 6}
• B. {3, 5}
• C. {2, 3, 4}
• D. {4, 5, 6}

Answer 1

The correct option is B {3, 5}

Given,

$A=\{3,5\}$

$B=\{2,3,4\}$

$C=\{4,5\}$

$⟹B\cup C=\{2,3,4,5\}$

Also, $A\cap (B\cup C)=\{3,5\}$.
