Work Step by Step
The sentence in "if...then" form is: If a vehicle has no flashing light on top, then it is not an ambulance.
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 a vehicle is not an ambulance, then it
has no flashing light on top. The inverse: If a vehicle has a flashing light on top, then it is an ambulance. The contrapositive: If a vehicle is an ambulance, then
it has a flashing light on top.
