State the converse, inverse and contrapositive of "If it rains, the match is cancelled", and say which is logically equivalent to the original.
Propositional Logic
Original Khojo Papers practice question — not from a past board paper.
It is a tautology: the expression is true in all four rows.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Whenever p ∧ q is true, p must also be true, so the implication can never have a true antecedent with a false consequent.
From the same topic and chapter, at a similar level.
