Confusion between implication with its converse.
I have given two propositions p: You drive over 65 mph q: You get a speeding ticket Here are two natural language statements Driving over 65 mph is sufficient for getting a speeding ticket (answer key: $p \to q$) Whenever you get a speeding ... , anything that comes after when/whenever is the antecedent, it should be $p \to q$. Where I am wrong here?
