Answer
See below.
Work Step by Step
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 some people are not hard workers, then all hard workers are successful. The inverse: If some hard workers are unsuccessful, then some people are not hard workers. The contrapositive: If all people are hard workers, then some hard workers are unsuccessful.
