I'm trying to find a function [possibly a way to make a function] which
calculate the sum of the elements of a list.
Right now, the purpose is to find the relative distribution of the
elements of a list. That is, I need a way to get out that the
distribution of:
{2, 2, 1}
is
{2/5, 2/5, 1/5}.
Had I been able to get the sum of the list elements in this way:
Sum[{2, 2, 1}]
it could had been done with:
l = {2, 2, 1}
l / Sum[l]
