Read Solution (Total 4)
-
- possible combi:
6,3,1 =3!
6,2,2= 3!/2!
5,4,1=3!
5,3,2=3!
4,4,2=3!/2!
4,3,3=3!/2!
prob= 27/216 - 11 years agoHelpfull: Yes(32) No(0)
- 3 dice are rolled so total of 216 possibilities are there.out of which sum should be 10..the possibilities are
(6,1,3)=6ways
(6,2,2)=3ways
(5,3,2)=6ways
(5,4,1)=6ways
(4,4,2)=3ways
(4,3,3)=3ways.
hence there will be a total of 27 whose sum is 10..
hence the ans would be 27/216 - 11 years agoHelpfull: Yes(6) No(0)
