Best Odds?

Say you have 10 armies and 3 territories linked together. What presents a better defensive scenario?
1) 8 on one territory, 1 on each of the others
2) 6 on one territory, 2 on each of the others
3) evenly split, with 4, 3, and 3 on the territories
Also, does it matter in which order they are placed? Is there an advantage to placing your largest army last or first?
This is not a strategical question, simply a mathematical one.
