Answer:
five or more than five
Explanation:
From the chart, we know that,
Number of children who chose soccer = 7 (this was the highest)
Number of children who chose swimming = 3
So for swimming to be chosen the most, it should gave been chosen by more than 7 children, i.e. 8 children or more than 8.
So the difference between 8 children and 3 children is = 8 - 3
= 5
Thus, 5 is the least number of other children to chose swimming.
Therefore, Sam asked at least 5 number of children or more than 5.
