Exam CRT-450 topic 1 question 177 discussion

A developer created this Apex trigger that calls MyClass.myStaticMethod: trigger myTrigger on Contact(before insert)
{ MyClass.myStaticMethod(trigger.new, trigger.oldMap); }
The developer creates a test class with a test method that calls MyClass.myStaticMethod, resulting in 81% overall code coverage.
What happens when the developer tries to deploy the trigger and two classes to production, assuming no other code exists?
