find the E[X1+X2+...+Xn]=?
Homework Equations
The Attempt at a Solution
Why can't I do this?:
E[X1+X2+...+Xn]=n*E[X1]
and just find the expected value?
Is that because the distribution changes as we increase the number of elements of uniforms we sum?
Is there some trick here?
I found something called "Irwin–Hall distribution"... is this it?
