If three, standard, 6-faced dice are rolled, what is the probability that the sum of the face up integers is \(12\)?

We have   6^3   =  216 possible outcomes

 

Ways of rolling 12

4 , 4, 4  =  1

4, 5 , 3  = 3! =  6

4 , 6 , 2  = 3!  =  6

5, 6 ,1  = 3! =  6

5 , 5 , 2 =  3

6 , 3 , 3  =  3

                 ___

                  25

 

P (12)  =   25  / 216
