If A = { 1, 2, 3, 4, 5, 6}, B = { 2, 4, 6, 8 }. Find (A – B) ⋃ (B – A).
A
{1, 3, 5, 8}
B
{8}
C
{1, 2, 3, 4, 5, 6, 8}
D
{1, 3, 5}
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
A = { 1, 2, 3, 4, 5, 6}
B = { 2, 4, 6, 8 }
A - B = { 1, 3, 5 }
B - A = { 8 }
∴ (A - B) ⋃ (B - A) = {1, 3, 5, 8}
