The law of large numbers #1

In a fair coin toss, the probability of head and tail is 50%:50%.
Why then, as i does this coin toss once, it ends up with real life result as 100% head and does not resembles at all - the initial probability value?

Take a moment to think about this seemingly stupid question because quite often in life, the key lies in them.

The answer is... Because i only toss the coin once!

The law of large numbers says that the more you toss the coin, the closer the end result would be to the expected value (50%)

I went on to toss a coin more than 4000 times, the result was recorded to be 50.54%:49.46%. Now that's pretty close to 50%.

As the picture above suggests, in real life practice it resembles more of an unstable electric wave, where the result falls around a certain range.
The more your repetition, the more narrow the range will be.
