There is a cube with 6 equal sides. You roll the cube 4 times. How much permutations of possible numbers can be, if it's known that the sum of the 4 numbers in the 4 rolls is equal to 18?
I tried to make a 6*6 chart with the numbers 1-6 on each side, but not all the possible combinations were there.
Someone else (I am not sure) solved it with some type of distribution, but the friend who asked the question said that this is not an efficient way.
Maybe it's out of my knowledge in math, or maybe I need some creative thinking, but I lack of this .
Can someone help me?
