A Combinatorics Problem D;

The final score of a table tennis game is 11 : 6. In how many ways can this total score be achieved?
SOLUTION: 8008


On the other hand,
Given 8 numbers 77889911, how many 8-digit numbers can be form?
SOLUTION: First we assume that the 8 digits are distinct so that the number of permutation is 8!.
As there are two ‘7’,two ‘8’, two ‘9’s and two ‘1’s, the answer is 8!/(2!2!2!2!) .


back to the first problem,

i assume that it's asking:
(WLOG)
WWWWWW ( win x 6) LLLLLLLLLLL ( lose x 11)

then the answer should be 17!/(11!6!) = 12376

but i'm wrong... (sigh)
is that i have misunderstood the question??

please help .__.
