Q59.The negation of the Boolean expression x ↔~y is equivalent to: (1) (~x ∧y) ∨(~x ∧~y) (2) (x ∧y) ∨(~x ∧~y) (3) (x ∧~y) ∨(~x ∧y) (4) (x ∧y) ∧(~x ∨~y)

What This Question Tests

This problem tests the understanding of logical equivalence and how to negate a biconditional statement, often solved using truth tables or known equivalences from Boolean algebra.

Concepts Tested

Logical connectives (biconditional, negation, conjunction, disjunction)Truth tablesLogical equivalence

Formulas Used

p ↔ q ≡ (p → q) ∧ (q → p)

p ↔ q ≡ (p ∧ q) ∨ (~p ∧ ~q)

~(p ↔ q) ≡ p ↔ ~q

~(p ↔ q) ≡ (p ∧ ~q) ∨ (~p ∧ q)
