Which of the following statement is false: A. A - B = A ⋂ B'B. A - B = A - (A⋂ B)C. A - B = A - B'D. A - B = ( A ⋃ B) - B |
Answer» A is true statement because A∖B is the set of elements which are in A but not in B ⇒A∖B is the set of elements which are in A and in B' ⇒A∖B is the set of elements of A⋂B' ∴A∖B = A⋂B' B is true statement because A∖B is the set of elements which are in A but not in B ⇒A∖B is the set of elements which are in A but not in A⋂B' ⇒ A∖B = A∖(A⋂B') C is false statement because A∖B = A⋂B' and A∖B^'= A⋂B ∴ A⋂B'≠A⋂B ⇒ A∖B≠B∖A. |
