mysteryman said: 16 minutes is incorrect :( Are there constraints for the dice colouring problem? I'm assuming that one may colour each die face one solid colour only, and that the die pips aren't to be coloured. I would say 4096 combinations (assuming that the die is a different colour to the paints) |
Good. A little harder: A random cube, you have 6 colours, and each side must be painted witth a different colour.

By a "random" cube are you saying that the cube is different in colour to all the paints you have available?
In that case there'd be 5040 combinations.
