যদি A = {1, 3, 5, 7, 9} এবং B = {1, 2, 3, 4, 5} হয়, তাহলে (A ∪ B) - (A ∩ B) =?

প্রশ্ন: যদি A = {1, 3, 5, 7, 9} এবং B = {1, 2, 3, 4, 5} হয়, তাহলে (A ∪ B) - (A ∩ B) =?

সমাধান:
A = {1, 3, 5, 7, 9} এবং B = {1, 2, 3, 4, 5}
A ∪ B = {1, 2, 3, 4, 5, 7, 9}.

A ∩ B = {1, 3, 5}.

(A ∪ B) - (A ∩ B) = {1, 2, 3, 4, 5, 7, 9} - {1, 3, 5}
= {2, 4, 7, 9}
