Question 948778
There are 216 possible outcomes when you roll three dice from 1-1-1 to 6-6-6. 
So all possible sums falls between the range of 3 and 18. 
So the probability of getting a 19 is 0. It is not possible. {{{P=0/216=0}}}
The probability of getting between 3 and 18 is 100%. It will always happen.{{{P=216/216=1}}}
