Do there exists two humans on earth with exactly the same amount of hairs on their body? I have heard of this pigeonhole principle that explains that this is indeed the case, but I don't really get the argument.<|im_end|>

The pigeonhole principle states that if you have more items than containers, then at least one container must contain more than one item. This principle can be applied to the number of hairs on a human body by considering the number of hairs as items and the possible number of hairs as the containers.

Assuming that the average human has approximately 5 million hairs on their body, we can use the pigeonhole principle to conclude that there must be at least two people with the same number of hairs on their body. The reason for this is that there are only a limited number of possible numbers of hairs a person can have (for example, 4 million, 5 million, 6 million, etc.). If we have a large enough population, it is likely that there will be at least two individuals with the same number of hairs, even if the number of hairs is distributed randomly.

In conclusion, it is possible for there to be two people with exactly the same number of hairs on their bodies, and the pigeonhole principle provides a mathematical explanation for this phenomenon.<|im_end|>

Is this similar to the law of very large numbers?<|im_end|>

The Pigeonhole Principle and the Law of Large Numbers are related but they are not the same thing.

The Pigeonhole Principle is a mathematical principle that states that if you have more items than containers, and you distribute the items randomly into the containers, at least one container must contain more than one item.

The Law of Large Numbers is a statistical theorem that describes the behavior of the average of a large number of independent, identically distributed random variables. The theorem states that as the number of observations increases, the average of the observed values converges to the expected value.

In the case of the number of hairs on a human body, the Pigeonhole Principle suggests that since there are more people on earth than there are possible numbers of hairs on a human body, it is likely that at least two people have the same number of hairs. The Law of Large Numbers, on the other hand, is not directly relevant to this question, since it concerns the behavior of averages of large numbers of random variables, rather than the distribution of a single variable among a large population.<|im_end|>
