• The situation is similar to placing 10 identical balls among 5 distinguishable boxes, where a box may have zero or more balls in it.
  This case can be represented as arranging ten balls and (5-1) four walls in the single row, which can be done in 14C4 ways.(The balls placed between every successive pair of walls belong to one group) 14C4= 1001 ways.
