    p q r p->q ~p ~p->r [p->q] V [~p->r]

    T T T T F T T

    T T F T F F T

    T F T F F T T

    T F F F F F F

    F T T T T T T

    F T F T T F T

    F F T T T T T

    F F F T T F T

    A conditional statement (p ->q) is False only when q (the consequent) is false.

    So for column 6 (~p -> r), it will be False only when r is false.

    Disjunctions (p V q) are False only when both p and q are False.

    So column 7 ([p->q] V [~p->r] is False only when both [p->q] and [~p->r] are False.
