Twenty-seven identical white cubes are assembled into a single cube, and the outside of that cube is painted black.
The cube is then disassembled and rebuilt randomly.
What is the probability that the outside of this cube is again completely black?
(In reply to re(3): solution
2 orientations out of 24 work for the face edges = 1/12
