उत्तर

p q r ∼p ∼q p ∨ ∼q ∼p ∧ q (p ∨ ∼q) ∨ (∼p ∧ q) (I) ∧ r
              (I)  
T T T F F T F T T
T T F F F T F T F
T F T F T T F T T
T F F F T T F T F
F T T T F F T T T
F T F T F F T T F
F F T T T T F T T
F F F T T T F T F

The entries in the last column are neither all T nor all F.
∴ [(p ∨ ∼q) ∨ (∼p ∧ q)] ∧ r is a contingency.
