Truth table of (p or q) and (not p or q) and (p or not q) and (not p or not q)

Step by step

  1. \left(p \vee q\right) \wedge \left(p \vee \neg q\right) \wedge \left(q \vee \neg p\right) \wedge \left(\neg p \vee \neg q\right)

    2 variable(s) → 4 rows. Fill in every combination.

  2. \

    A contradiction (never true).
