i think so :) that's indeed a common definition

revised Is $\mathrm{span}\{v_1,v_2,v_3\}=\mathrm{span}\{v_1+v_2,v_1+v_3,v_2+v_3\}$ if $v_1,v_2,v_3\in V$ a vector space over $\mathbb{Z}_2$?

yes, you got it right

comment You can always delete a vertex from a tree $G$ such that the remaining connected components have size at most $|V(G)|/2$.
one hunch is try to a proof by induction, possibly deleting a leaf, but not sure if it will help.

comment What is the domain and range of the sum of two random variables?
@Did perhaps i see the difference -- you want to define $S(\omega) = X_1(\omega) + X_2(\omega)$ where all variables map from $\Omega^n$, but each $X_i$ only uses the $i$th coordinate. Why would this make impossible every simple operation? We just defined addition, you can define integration and scalar multiple and everything else analogously -- why does this cause a problem? Please understand, I am not arguing, just asking for clarification for my own education. Thanks
