Find the average of the numbers appearing on all 6 faces of a cubical die numbered 1 to 6.

3.4 3.2 3.5 3.6

3.5

Numbers appear on all faces of cubical dies = 1 , 2 , 3 , 4 , 5 , 6, First number = 1 , Last number = 6 Average = \(\frac{First\; term \;+\; Last \;term}{2}\) = \(\frac{1 \;+\; 6}{2}\) = \(\frac{7}{2}\) = 3.5
