Answer 2

Answer: Option B

4.72%

Explanation:

We know that the total number of couples surveyed was 1250

Now identify the lowest frequency and divide it by the total of couples surveyed

The lowest frequency is that corresponding to 5 children or more.

The percentage is:

`(59)/(1250) *100\%=4.72\%`

Only 4.72% of couples surveyed have 5 children or more

The answer is the option B
