Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
This reads like a homework/exam/etc. question taken directly from the worksheet, exam paper or similar. If you are not a student trying to get other people to do assigned work for you, I apologize for the misconception, but you should probably re-word the question to give the context in which you are asking.
If you are a student trying to get other people to do assigned work for you, please don’t. It is dishonest and will probably not benefit you in the long run. If you are looking for help to understand how to approach answering the question, as opposed to for someone to simply give you the answer and/or detail all the steps to work out the answer, then please re-word the question to reflect this.
