What is the origin of the standard normal distribution function?

Click For Summary
SUMMARY

The standard normal distribution function, represented as Φ(x) = e^(-x²/2) / √(2π), originates from the central limit theorem, a fundamental theorem in probability theory. This theorem states that the sum of a large number of independent random variables tends toward a normal distribution, regardless of the original distribution of the variables. Understanding this relationship is crucial for statistical analysis and applications in various fields.

Hello,
Where does the standart normal distribution function

[tex]\Phi (x)=\frac{e^{-\frac{x^2}{2}}}{\sqrt{2\pi }}[/tex]

come from?I wonder it.Please explain to me.Thanks for your helps.

It comes from the central limit theorem, one of the most important theorems in probability theory. Look it up on google.
