I'm confused on this. Bunuel Can you post the solution?

Aren't there 7 possible scenarios of all black and white squares?

IMO, the first die and the second die have different number of solid Black surfaces. hence, needs to be deal indivisually.

die 1: 1- p(getting solid black or solid white)
1-1/2 { 1/2= (2/6+1/6) <<(2 black surface out of 6 and 1 white surface out of 6 total surface)
=1/2

die 2: 1-2/3 {2/3= 3/6+1/6} << 3 black and one white surface out of 6)
=1/3

P(neither gives in solid black/white) = 1/2*1/3=1/6 Answer.

Take Cardboard piece 1,
Probability of not a solid black or solid white P1 = 3/6=1/2

Take Cardboard piece 2,
Probability of not a solid black or solid white P2= 2/6=1/3

Required probability = Probability neither cardboard piece show solid black or solid white = P1*P2= (1/2)*(1/3)=(1/6)

Hence A
