Hello. It is very easy. Law of large numbers requires that <math>X_1,X_2,\dots</math> are independent (i.e. every finite subset of them is independent). Yet, a child has usually similar properties to an adult. Therefore <math>X_{i+1}</math> is not independent of <math>X_{i}</math>. It does not mean they are perfectly correlated - a child might sometimes be different from its parent. But they are definitely not independent, and therefore you cannot use the law. Using a mathematical theorem when assumptions are not fully satisfied will easily give you absurd conclusions - think what happens if you to use Pythagorean theorem in an acute triangle. --[[User:Cipe|Cipe]] 15:54, 17 March 2012 (EDT) | Hello.
