Large numbers Quote by Anonymous
““Coins have no memory. So the next coin you flip has a 50-50 chance of coming up heads, the same as any other. The way the overall proportion settles down to 50% isn’t that fate favors tails to compensate for the heads that have already landed; it’s that those first ten flips become less and less important the more flips we make. If I flip the coin a thousand more times, and get about half heads, then the proportion of heads in the first 1,010 flips is also going to be close to 50%. That’s how the Law of Large Numbers works: not by balancing out what’s already happened, but by diluting what’s already happened with new data, until the past is so proportionally negligible that it can safely be forgotten.””

Source Lecture: Probability Theory, 2020
The law of large numbers shows that as more trials occur, the average outcome converges to the expected probability, making early results negligible.
In simple terms: More flips make early results irrelevant, stabilizing the average.

A Different Perspective
It assumes independent, identically distributed trials; real-world data may be biased.
