Need help with a math question

Answer 1

Answer:

57%

Step-by-step 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 3, 4 or 5 people.

Frequency of families with 3, 4 or 5 people = 200 + 245 + 125 = 570

Total frequency = 1000

P (families with 3, 4 or 5 people) = (570 / 1000) × 100 = 57%
