Answer:
80%
Explanation:
We are given the results of survey of one thousand families to determine the distribution of families by their size.
We are to find the probability (to the near percent) that a given family has more than 6 people.
Frequency of people with less than 5 people = 350 + 200 + 245 = 795
Total frequency = 1000
P (families with fewer than 5 people) = (795 / 1000) × 100 = 79.5% ≈ 80%
