Answer: Option 'B' is correct.
Step-by-step explanation:
Since we have given that
A circle is divided into 9 uneven pie shaped pieces.
Each section is labeled 1 to 9.
When the circle is spun and the number pointing north it will be recorded:
4 3 2 1 9 8 5 6 7 4 3 2 1 5 8 6 5 4
We need to find the central angle of the section labeled 4.
Number of times 4 occur= 3
Total number of times it has been recorded = 18
So, Probability of getting "4" is given by

Hence, Option 'B' is correct.
