We roll five standard dice (sides numbered 1 to 6) and write down the sum of the top three i.e. of the 3 highest values.
What is the probability to get 15 ?

(In reply to analytical attempt at it by Vishal Gupta)

In your addition of the ways of getting 6,3,3, you forgot the word "each" in two places, and didn't multiply by 2.

60 + 2*30 + 2*30 + 10 = 190, rather than 130.
