## Thinking Mathematically (6th Edition)

The contrapositive of $p\rightarrow q$ is $\sim q\rightarrow p$. The converse of $p\rightarrow q$ is $q \rightarrow p$. The inverse of $p\rightarrow q$ is $\sim p\rightarrow q$. Hence here the converse is: If you die, you don’t laugh. The inverse: If you laugh, you don’t die. The contrapositive: If you don’t die, you laugh.
