Prepare a table, and calculate the sum of frequencies as shown below.

The number of times the score was 2 was 6 times.

The sum of frequencies or the total number of times the dice was rolled is 20.

The total angle of a circle is 360^\circ

So the angle of the sector of the pie chart representing the score of 2 = \frac{6}{20}\times 360^\circ = 108^\circ
