I need help with this problem please.

Answer:
15 adults were questioned.
33.3% had 2 children.
Step-by-step explanation:
To find the number of adults add all the number of adults for each number of children. For example 2 adults had 0 children.
To find the percentage
100/15= 6.66
6.66× 5= 33.3
Answer:
15 adults were questioned. (2+4+5+1+1+2) (y-axis)
5 of the 15 adults had 2 children = 5/15 = 1/3 = 33,3%
