Answer:
b. How many families have at least 2 students enrolled in school year
2020-2021?
ĂNSWER: To calculate the number of families with at least two students enrolled in school, we can add the number of families with two students, three students, and four or more students.
Total number of families with at least two students enrolled = Families with two students + Families with three students + Families with four or more students
= 720 + 60 + 180
= 960
Therefore, 960 families have at least two students enrolled in school year 2020-2021.
c. How many families have less than 4 household members enrolled in
school year 2020 - 2021?
ĂNSWER:To calculate the number of families with less than four household members enrolled in school year 2020-2021, we can add the number of families with less than three members, three members, and four or more members.
Total number of families with less than four household members enrolled = Families with less than three members + Families with three members + Families with four or more members
= 280 + 100 + 340
= 720
Therefore, 720 families have less than four household members enrolled in school year 2020 - 2021.
