Solution

The correct option is D 44100

To evaluate the relative frequency, two things must be known:
Number of total events/trials
Frequency count for a category/subgroup

Relative frequency can be calculated as:
Relative Frequency=Subgroup frequencyTotal frequency


In the given question,
Total number of people = Number of vegetarian people + Number of non-vegetarian people

Total number of people=56+44
Total number of people=100

Number of non-vegetarian people=44

Relative frequency of a person in town being non-vegetarian
=44100

Therefore, option (d.) is the correct answer.
