A die is rolled 240 times with the results below. If a pie chart is constructed to represent the data, the angle corresponding to 4 is

No.	1	2	3	4	5	6
Frequency	30	43	54	40	41	32

Worked solution (try it first)

The die was rolled 240 times, so each roll gets $\frac{360^\circ}{240} = 1.5^\circ$ .
The number 4 came up 40 times: $40 \times 1.5^\circ = 60^\circ$ , option D.
