TossCoin

Coin lật, đồng xu ném, hoặc người đứng đầu hoặc đuôi là thực hành ném

Coin flipping, coin tossing, or heads or tails is the practice of throwing a coin in the air to choose between two alternatives, sometimes to resolve a dispute between two parties. It is a form of sortition which inherently has only two possible and equally likely outcomes.
