@Enigma001 Arey jab Red OR Blue hoga, tabhi to 10 aayega. Why are you multiplying 3R and 3B by 2? If it is red AND blue, tab to 8 aayega because all Red and all Blue are removed from the list.
n wats wrong with my appraoch:
u can choose any face in 6c1 way n colour it in 2c1 way
next face can be chosen in 5c1 way n colured in 2c1 way again
Basically what you have to do is paint the cube using 2 colors R and B :
Case 1 : 5faces R,1 face blue and vice versa : 1*2 =2
Case 2: 4 faces R, 2 faces blue and vice versa :2*2 = 4
Case 3: 3R,3B and vice versa : 4 cases
ek doubt he..4R and 2b wala case he..usme bhai khud hi me do case banenge..jab 4 r maanlo walls pe hi ho..floor and celing pe nhi n one when they ARE MUTUALLY ADJACENT
@Brooklyn Arey I was referring to @Enigma001 's post. He calculated 12 cases for Red OR Blue waala situation. I think it will be only 10. I recommend drawing a figure to visualize...
1. All faces red - Only 1 way of doing this
2. All faces blue - Only 1 way of doing this
3. 5 R + 1 B. Only one way of doing this. Also, since R and B can be interchanged to get 5B +1R as another case, we multiply by 2.
4. 4 R + 2 B. There are two ways of doing this: one with the blue faces opp each other and another with blue faces adjacent to each other. Again, R & B can be interchanged so multiply by 2.
5. 3R + 3B. There are two ways of doing this: In one case each red face pair shares an edge and all 3 of them share a vertex. In the other case 2 of the red faces are opposite each other and do not have any common edge. Blue will occupy all the other 3 sides in either case.
Now this case does not have to be multiplied by 2, because 3R+3B = 3B+3R and we will get the same cases.

arey jab red or blue hoga to that means you can paint the cube either by red or by blue plus the combination of both whereas red and blue matlab r and b dono hi use honge ONLY
basically maine 2 se isliye multiply kia kyunki aise cases banenge 4r 2b and 2r 4 b and so on.Kya confusion hai ismein ?
