U = {a, b, c, d, e, f, g, h}, A = {a, b, c, d, e}, B = {b, d, f, h} হলে, A´ ∩ B´ হবে?

প্রশ্ন: U = {a, b, c, d, e, f, g, h}, A = {a, b, c, d, e}, B = {b, d, f, h} হলে, A´ ∩ B´ হবে?

সমাধান:
A´ = U - A
= {a, b, c, d, e, f, g, h} - {a, b, c, d, e}
= {f, g, h}

B´ = U - B
= {a, b, c, d, e, f, g, h} - {b, d, f, h}
= {a, c, e, g}

∴ A´ ∩ B´ = {f, g, h} ∩ {a, c, e, g}
= {g}
