Question 1.

Two dice are placed side by side as shown. Can you say what the total would be on the face opposite to?

(a) 5 + 6

Solution:

Here, the face opposite to the face having 5 dots is the face having 2 dots, and the face opposite to the face having 6 dots is the face having 1 dot.

So, the total on the face opposite to 5 + 6 is 2 + 1 i.e., 3.

(b) 4 + 3

Solution:

The face opposite to the face having 4 dots is the face having 3 dots and the face opposite to the face having 3 dots is the face having 4 dots.

So, the total on the face opposite to 4 + 3 = 3 + 4 i.e., 7.
