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 it is not an apple, then it is blue. The inverse: If it is not blue, then it is an apple. The contrapositive: If it is an apple then it is not blue.
