যদি A = {1, 2, 3, 4} এবং B = {3, 4, 5, 6} হয়, তাহলে A

যদি A = {1, 2, 3, 4} এবং B = {3, 4, 5, 6} হয়, তাহলে A - (A ∩ B) এর মান কত?

A {1, 5}

B {2, 3}

C {1, 3}

D {1, 2}

Correct Answer: Option D

A ∩ B = {3, 4}
A - (A ∩ B) = {1, 2, 3, 4} - {3, 4} = {1, 2}
A - B = {1, 2, 3, 4} - {3, 4, 5, 6} = {1, 2}

সুতরাং A - (A ∩ B) = A - B = {1, 2}
