What are the possible results of throwing a uniform coin at will? Is the possibility of each result the same? This method is fair.

There will only be two outcomes, positive and negative, and the probability of each is zero. This is a classic binomial distribution. It is fair to make a judgment. Of course ... this situation is like a coin standing ... very small. Usually not once in tens of millions of times.

However, in real life ... the patterns on both sides of the coin are different, the quality is uneven, and there are interference factors such as wind resistance. When the coin is tested to a certain value … it will be slightly larger than 1/2.
