i) At least two empty box.
# of ways to select 2 distinct boxes: 10*9 = 90
---
# of ways to arrange 20 in the 8 remaining distinct boxes:
20P8 = 5079110900
------------------
Ans: 90*5079110900 = 4.5712x10^11
============================================
ii) No empty box.
20P10 = 20!/10! = 6.7044x10^11 ways
============================================
