 Mar 18 asked Minimizing percentiles of discrete distribution Mar 18 answered Show that $\exp(-\lambda x) \cdot\exp(\lambda x)=1$ using the power series Mar 18 comment Covering space of a graph is again a graph - why?? unfortunately not... haven't seen this in 3 years... Mar 18 comment Covering space of a graph is again a graph - why?? @Zero unfortunately not Mar 16 comment Central limit theorem for distribution peak rather than mean yes, thank you very much Mar 16 comment How to find this area by integration? are you looking for area and not volume? so surface area then? Mar 16 comment Central limit theorem for distribution peak rather than mean i couldn't get what you are asking -- the CLT does not depend on the underlying distribution of the $X_i$, it can be asymmetric or even discrete.

(4) is correct, (3) I am not sure.
