You and your friend are put in two different rooms with just a coin and no way to communicate. You both toss the coin at the same time.
Your task is for at least one of you to guess correctly what the other one has tossed. You may think ahead of a strategy that will help you.
note: The coins are regular H/T. There is no way to communicate after you enter the rooms, and you can't hear what the other one said. This is a logical question, not tricky.
