The statement (p∧(~q))∨((~p) ∧ q) ∨((~p) ∧ (~q)) is equivalent to _____

  • A
    ~p∨q
  • Correct answer
    B
    ~p∨~q
  • C
    p∨~q
  • D
    p∨q

Solution

Given,

(p∧(~q))∨((~p) ∧ q) ∨((~p) ∧ (~q))

=((~p) ∧ q) ∨((~p) ∧ (~q))∨(p∧(~q))

=~p∧q∨~q∨p∧~q

We know that ~A∨A=T, where T is tautology,

=~p∧T∨p∧~q

=~p∨p∧~q

=~p∨p∧~p∨~q

=T∧~p∨~q

=~p∨~q

Hence, the correct answer is option: 'B'.
