PzS?l'Q^,V6_K ?A;]DG (m4)^F0]gVE$V?N%(O8)T Take iid $X_1, ~X_2,~X.$ You can indeed talk about their sum's distribution using the formula but being iid doesn't mean $X_1= X_2.~X=X;$ so, $X+X$ and $X_1+X_2$ aren't the same thing. A 2volt nonrechargeable battery in constant use has a mean of 500 and a deviation. Because the normal distribution approximates many natural phenomena so well, it has developed into a standard of reference for many probability problems.

Use MathJax to format equations. This answer notes that if a programming language/libraries provide a procedure that returns random samples from a standard normal distribution, we can generate samples from another normal distribution with the same mean by multiplying the samples by the standard deviation of the desired distribution. Then: G ( y) = P [ Y y] = P [ c X y] = P [ X y c] = F ( y c) Now we differentiate and we get: g ( y) = f ( y c) 1 c. where g is the density function for Y and f is the density function for X.
