If $3$ dice are thrown together the no. of ways in which the sum of numbers appearing on the dice is $n$, is? $ \ $ $9 \leq n \leq14$

My try: $(x^1+x^2+x^3+x^4+x^5+x^6)^3$

The sum of the coefficients of $x^9$ to $x^{14}$ should be found. But I am getting stuck up in calculations. Now I have started doubting this method.

Clarifying your question... You seek the total number of ways to roll three dice and get sums of 9 through 14, inclusive. Correct? – Tim Thayer Feb 23 '17 at 16:30
Yes,you got it right. – Amit Hegde Feb 24 '17 at 03:53
Your approach should work. Please show your efforts. – Tim Thayer Feb 24 '17 at 16:26
