From: 2.7182818284590... on 9 Mar 2010 17:11 What is the relationship between the Gaussian Curve and the coefficients of Pascal's Triangle? When I plot the coefficients of PT for the 15th row, it looks very much like a Gaussian Distribution. 1 16 16 15 120 14 560 13 1820 12 4368 11 8008 10 11440 9 12870 8 11440 7 8008 6 4368 5 1820 4 560 3 120 2 16 1 1 0 So how are these two phenomenon's related? Coincidentally, or is the Binomial Distribution the basis for the Gaussian Distribution?

You have noticed something that was known to De Moivre back in 1738; see the De Moivre Laplace Limit Theorem, http://en.wikipedia.org/wiki/De_Moivre%E2%80%93Laplace_theorem or http://mathworld.wolfram.com/deMoivre-LaplaceTheorem.html .

Do you know where I can find the proof of this (i.e. Gaussian Distribution is a Binomial Distribution with infinity outcomes)?
