Let's just assume that one dice is blank and settle on 1/12 for two others?

Not sure if you had this in mind while giving the solution, but here it goes.

the reason why your soln worked is because then P(3) = P(18) , P(4) = P(17) etc ( where P(n) is the probability of getting a total of n)

hence the P(n<=10) = P(n > 10).

Yep, if we assume symmetry of the outcome distribution than the answer is indeed 0.5

addition: just checked the distribution, it's indeed symmetric

3 0.46 %
4 1.39 %
5 2.78 %
6 4.63 %
7 6.94 %
8 9.72 %
9 11.57 %
10 12.5 %
11 12.5 %
12 11.57 %
13 9.72 %
14 6.94 %
15 4.63 %
16 2.78 %
17 1.39 %
18 0.46 %

for me it's clear

3 is minimum possibility
18 is the maximum one
total number of values : 16 (18-3+1)
so answer should be 8/16 -> 1/2
