The combination of 10 can occur when we have (1,3,6) (1,4,5) (2,2,6) (2,3,5) (2,4,4) (3,3,4) = 6 patterns.
(1,3,6) can be 1,3,6 or 1,6,3 or 3,1,6 or 3,6,1 or 6,1,3 or 6,3,1 that is in 3! ways
Set having repeating digits like 2,2,6 can be ordered in 3!/2 ways = 3 ways (like 2,2,6 or 2,6,2 or 6,2,2)
Hence over all occurrences = 6 + 6 + 3 + 6 + 3 + 3 = 27 ways.
Probability = 27/216 = 3/24 = 1/8
