U = {1, 2, 3, 4, 5, 6} , A = {1, 2, 3} , এবং B = {2, 4, 6} হলে (A‘ ∩ B‘) এর মান কত?

প্রশ্ন: U = {1, 2, 3, 4, 5, 6} , A = {1, 2, 3} , এবং B = {2, 4, 6} হলে (A‘ ∩ B‘) এর মান কত?

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

A‘ = U - A
= {1, 2, 3, 4, 5, 6} - {1, 2, 3}
= {4, 5, 6}

B‘ = U - B
= {1, 2, 3, 4, 5, 6} - {2, 4, 6}
= {1, 3, 5}

∴ (A‘ ∩ B‘)
= {4, 5, 6} ∩ {1, 3, 5}
= {5}
