Is it really fair to throw a coin?
In real life, the probability of a real coin being both positive and negative is not entirely 50/50. Because of the difference in the design, weight distribution of the coins on both sides, and the starting state of the throwing, the experiment showed a slight deviation (about 51 per cent positive) in the real coins. And our online tools use browsers.
crypto.getRandomValues()
A secure, secure random number generator, which provides a real, unbiased, 50/50 random probability, is fairer and more credible than a physical coin.
When should we use coins to make decisions?
- When both options are equally good: If you're facing two options, either one of them is acceptable, the coin-throwing is the fastest way to eliminate the difficulties of choice.
- When trying to test internal orientation: When the coin falls, your first emotional reaction tends to reveal what you really expect.
- When the deadlock is broken: A fair coin-throwing can resolve the controversy.
- At the beginning of the sports competition: The right to start a game like football, basketball, etc. is usually achieved by throwing a coin.
- Play time: Tables and role-playing games are used when making random decisions
Psychological skills:
Before you throw a coin, you say, "I'll pick A on the front, I'll choose B on the back." When the results come out, look at your first reaction — if you are disappointed, it means you're subconsciously more interested in choosing another.
