Explanation / Answer

Answer

As the data given is specific yet ASSUMED to repeat,
the given problem falls in the category of
Discrete Random Variable.

For the likelihood that 6 or more people show up during a given day:
frequency of 6 people coming = 3 days
frequency of 7 people coming = 1 day
frequency of 8 people coming = 1 day

Total number of days taken for observation = 20 days

So,
Probability of 6 or more people showing up during a given day is
= 5/20
= 0.25

Therefore, (a) is the answer.
