    Ok make the chart for it but I will help you if you can give the exact problem and use ~ for non p

    For ex.

    ~p
    ~q

    p ~p
    T F
    F T

    q ~q
    T F
    F T

    p q (p∨q) ~(p∨q)
    T T T F
    T F T F
    F T T F
    F F F T

    Note: ~(p∨q) = ~p ∧ ~q

    Ok, fine ill try with this.

    P Q ~P ~Q P v Q ~P v ~Q
    T T F F T F
    T F F T F F
    F T T F F F
    F F T T F T

    When doing column three, look at column 1.

    When doing column four, look at column 2.

    When doing column 5, look at column 1 and 2

    When doing column 6, look at column 3 and 4.

    And follow the rules of conjunction and disjunction.
