동전을 이용하여 확률의 개념을 가르치는 일은 오랫동안 이루어져 왔으며, 통계 교과서에는 공정한 동전과 그렇지 않은 동전에 관한 많은 문제가 제시되고 있다. 그러나, 공정하지 않은 동전을 실제로 만나본 사람은 없는 것으로 알려져 있다. 본 연구에서는 확률 학습에 사용될 공정하지 않은 동전으로 가운데가 굽혀진 동전을 제시한다. 또한, 여러 가지 각도로 굽혀진 동전의 앞면이 나올 확률을 던지기 실험을 통하여 추정한다. 굽혀진 동전은 통계학 수업에서 공정하지 않은 동전을 다루는 경우에 실습용으로 사용될 수 있을 것이다.

The meaning of the amendment to the Media Arbitration Act in our society is not limited to media companies. And it's not just a problem for a specific group. It expresses public value because it is an issue that can affect members of society as a whole and furthermore, it becomes a bill that can infringe or strengthen individual freedom guaranteed by the Constitution, but makes different arguments. Freedom of speech is not achieved in a day and should not be easily lost by someone. Although it is not a frequent problem, fatal threats arising from wrong media reports take away an individual's present and future. It is because of this problem that the responsibility is important. Freedom of speech and control are heading in different directions, but they are the same as the front and back of the coin. The freedom pursued is different, but it consists of one body. If freedom and responsibility of speech made up of one body criticize or ignore each other, the results are scattered into a distorted On the other hand, the flexion of responsibility without freedom serves as a speaker that conveys the ideology of some classes or represents the interests of a particular group. The fact that the media should act as the air of society means that it should represent the interests of the majority, make them aware of the rights of unfair or marginalized members, and be their strength.
