Need help with math question

Answer 1

1.4%

Explanation:

You can only include 7 and 8 in the answer because it didn't include 6 in the question. add the frequency for both of those sizes (14) and divide by the total (1000) to get the probability. multiply by 100 to get answer as a percent. 1.4%

Answer 2

1%

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 (in percent) that a given family has more than 6 people.

Frequency of people with more than 6 people = 10 + 4 = 14

Total frequency = 1000

P (families with more than 6 people) = (14 / 1000) × 100 = 1.4% ≈ 1%
