If these 2037 tossing were closed to the theoretical result, and then the next 9 tossing all ended up head, what do you think about the next one? If you group tossing
at a time, you would likely found head and tail distributed according to binomial distribution, and 10 consecutive tossing all shown head is not that adnormal? It could heppen, only 1/1024, not that small.
The bottom line is 9 tossing is a too small sampling space to make conclusion, you don't even know what the result may have been before your orbservation. In
practical test, event the weight of a coin is not evenly
distributed between head and tail, the outcome is still pretty much 1/2.
