Directions (Q.8 & Q.9) : Sometimes we are given figures showing the same die in various positions. After
observing these figures, we have to find the number opposite a given number on the die. The procedure to be
adopted for solving such problems, will be clear from the following examples :
Example: A die is thrown four times and its four different positions are given below. Find the number on the
face opposite the face showing 2.
