Ex.14.2 Q7 Statistics Solution - NCERT Maths Class 9
The value of \(π\) upto \(50\) decimal places is given below:
(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?
What is known?
- The value of ‘\(π\)’ upto \(50\) decimel places.
What is unknown?
- Constructing a required frequency distribution table
- And finding the most and the least frequently occurring digits.
We can count each digit and can be written in front of them , like this we can draw frequency distribution table and can be concluded about most or least frequently occurring digits.
We can represent the data by constructing a simple, ungrouped frequency distribution table as follows.
|DIGITS||TALLY MARKS||FREQUENCY OF OCCURRENCE|
If can be easily observed from the table 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 a lowest frequency of \(2\).
