How many dots are contained on the face opposite to that containing four dots?   A) 2 B) 3 C) 6 D) Can’t be determined Ans. AWe shall assume the dice in fig. (ii) to be rotated so that the 5 dots appear at the same position as in fig. (i) i.e. on RHS face (i.e. on face II as per activity 1) and 1 dot appears at the same position as in fig; (i) i.e. on Front face (i.e. on face I). Then, from the, two figures, 2 dots appear on the top face (i.e. on face V) and 4 dots appear on the Bottom face (i.e. on face VI).Since, these two faces are opposite to each other, therefore, two dots are contained on the face opposite to that containing four dots.
