• A. 0

Answer 1

The correct option is A 0
Frequency is the number of occurrences of n repeated event, parameter, object or datapoint.

Here,
7 occurs 6 times, so 6 is the frequency of 7.

Similarly, 6 occurs 6 times.

Frequency of 6 is 6 and frequency of 7 is also 6.

Therefore, the difference of their frequencies is 0.
