how to draw 64 cubes
Answers
Answer:
The above answer (by "Mike") isn't quite right. Yes, there are 56 cubes with at least one side painted.
However, there is not an equal probability for any of the smaller cube's faces to appear. To understand why, it is best to approach the problem as follows:
8 cubes out of 56 have 3/6 faces painted (these are the corner cubes)
24 cubes out of 56 have 2/6 faces painted (these are the edge cubes)
24 cubes out of 56 have 1/6 faces painted (these are the remaining face cubes)
Thus, the probability of rolling a painted side, conditioning in the type of cube you pick, works like this:
P(painted)=P(painted | corner cube)P(corner cube) + P(painted | edge cube)P(edge cube) + P(painted | face cube)P(face cube) = (1/2)(8/56)+(1/3)(24/56)+(1/6)(24/56) = 2/7
