The value of π upto 50 decimal places is given below:
3.14159265358979323846264338327950288419716939937510
i) Make a frequency distribution of the digits from 0 to 9 after the decimal point.
ii) What are the most and the least frequently occurring digits?
Solution:
(i) We can represent the digits from 0 to 9 by constructing a simple, ungrouped frequency distribution table as follows.

(ii) It can be easily observed from the table that
 The most frequently occurring digits are 3 and 9, with a max frequency of 8.
 The least frequently occurring digit is ‘0’ with the lowest frequency of 2.

NCERT Solutions for Class 9 Maths  Chapter 14 Exercise 14.2 Question 7:
It is given that value of π up to 50 decimal places as 3.14159265358979323846264338327950288419716939937510. We have prepared an ungrouped frequency distribution table as given in the solution and found that the most frequently occurring digits are 3 and 9, with a max frequency of 8 and the least frequently occurring digit is ‘0’ with the lowest frequency of 2.
