Abstract
It is generally believed that teaching probability with the help of coin tossing has a long history. In textbooks about elementary probability or statistics, problems on unfair coins as well as fair ones are frequently given. However it is known that nobody has met an unfair coin with a fixed head probability which is different from 0.5 in flesh and blood. In this study a coin bent along with the middle line of the coin is suggested as an unfair one. By flipping bent coins with various angle, the ratios of head of the coins are obtained. The bent coins might be used as experimental tools for teaching of probability concept.
