Answer

After performing the specified steps on $p→q$ we get converse of its inverse $¬p$ $\rightarrow$ $¬q$ The converse of its converse $q→p$ The converse of its contrapositive $¬q→¬p$

Work Step by Step

the converse of its inverse By the definitions, we know that the inverse of $p→q$ is: $¬p→¬q$ The converse interchanges the compound propositions in the conditional statements: $¬q→¬p$ Note: the Converse of the inverse is the contrapositive. The converse of its converse By the definitions, we know that the Converse of $p→q$ is: $q→p$ the converse interchanges the compound proposition in the conditional statements: $p→q$ Note: the Converse of the converse results in the original conditional statement. The converse of its contrapositive By the definition, we know that the Contrapositive of $p→q$ is $¬q→¬p$ The converse interchanges the compound propositions in the conditional statements: Note: The Converse of the contrapositive is the inverse.
