Given that the various faces of a fair dice 1, 2, 3, 4, 5, 6 appeared 30, 43, 54, 40, 41, 32 times respectively in a single toss. Picture the figures as being represented in a simple table with number (X) against frequency (f).
If a pie chart is used to depict the data, the angle corresponding to 4 is?
If a pie chart is used to depict the data, the angle corresponding to 4 is?
10°
16°
40°
60°
Explicació
Angle corresponding to 4 is 40/240 x 360/1 = 60°
Note that total angle in a circle is 360°.
Note also that sum of the frequencies given is 240.
