U = {1, 2, 3, 4, 5, 6, 7}, A = {1, 2, 3, 6} এবং B = {3, 5, 7} হলে, A‘ ও B‘ = কত?

প্রশ্ন: U = {1, 2, 3, 4, 5, 6, 7}, A = {1, 2, 3, 6} এবং B = {3, 5, 7} হলে, A‘ ও B‘ = কত?

সমাধান:
দেওয়া আছে,
U = {1, 2, 3, 4, 5, 6, 7}
A = {1, 2, 3, 6}
এবং, B = {3, 5, 7}

A‘ = U/A = {1, 2, 3, 4, 5, 6, 7}/ {1, 2, 3, 6}
= {4, 5, 7}
B‘ = U/B = {1, 2, 3, 4, 5, 6, 7}/{3, 5, 7}
= {1, 2, 4, 6}

∴ নির্ণেয় সেট, A‘ = {4, 5, 7} এবং B‘ = {1, 2, 4, 6}
