যদি A = {1, 2, 3, 4, 5, 6}, B = {2, 3, 4, 6} এবং C = {1, 5, 6} হয়, তবে (A - B) ∪ C = কত?

প্রশ্ন: যদি A = {1, 2, 3, 4, 5, 6}, B = {2, 3, 4, 6} এবং C = {1, 5, 6} হয়, তবে (A - B) ∪ C = কত?

সমাধান:
দেওয়া আছে,
A = {1, 2, 3, 4, 5, 6},
B = {2, 3, 4, 6}
এবং C = {1, 5, 6}

এখন,
A - B = {1, 2, 3, 4, 5, 6} - {2, 3, 4, 6}
= {1, 5}

∴ (A - B) ∪ C
= {1, 5} ∪ {1, 5, 6}
= {1, 5, 6}
