If A 1 2 3 4 5 6 B 2 4 6 8 Find A B B A - JAMB Mathematics 2023 Question

Let's find \( (A - B) \cup (B - A) \), where \( (A - B) \) represents the elements that are in A but not in B, and \( (B - A) \) represents the elements that are in B but not in A.

\[ A - B = \{1, 3, 5\} \]
\[ B - A = \{8\} \]

Now, take the union of these two sets:
\[ (A - B) \cup (B - A) = \{1, 3, 5\} \cup \{8\} \]

The resulting set is \{1, 3, 5, 8\}.

Therefore, the correct answer is {1, 3, 5, 8}
