A group have in their families. The bar graph of adults were asked how many children they below shows the number of adults who indicated each number of children.How many adults were questioned?

Answer 1

If we add the frequencies of the histogram ( vertical axis), we get that the number of adults questioned is:

`4+7+5+3+1=20.`

Now, out of those 20, only 5 have 2 children, therefore:

`(5)/(20)*100=25\%`

have 2 children.

Answer:

20 adults were questioned,

25% have 2 children.
