The useful idea
- The useful idea
In probability theory, the law of large numbers is a mathematical law which states that the average of the results obtained from a large number of independent random samples converges to the true value,
- How it works
More formally, the law of large numbers states that given a sample of independent and identically distributed values, the sample mean converges to the true mean.
- Why it matters
The law of large numbers is important because it guarantees stable long-term results for the averages of some random events.
Why this matters
Use Law of large numbers as a quick check before trusting your first conclusion.
