Question

michal makes a table to show which of her friends have siblings. she counts 6 boys who have no siblings and 9 girls who have no siblings. she counts 10 friends who are boys and 18 friends who are girls. which table correctly shows the data?

first table:

	siblings	no siblings	total
girls	12	1	13
total	18	10

second table:

	siblings	no siblings	total
girls	9	1	10
total	15	13

third table:

	siblings	no siblings	total
girls	9	9	18
total	13	15

fourth table:

	siblings	no siblings	total
girls	4	9	13

Explanation:

Step1: Calculate boys with siblings

Total boys: 10; No siblings: 6.
Boys with siblings = $10 - 6 = 4$

Step2: Calculate girls with siblings

Total girls: 18; No siblings: 9.
Girls with siblings = $18 - 9 = 9$

Step3: Match to correct table

Verify totals: Boys total $4+6=10$, Girls total $9+9=18$.

Answer:

The third table (with rows: Boys: 4 siblings, 6 no siblings, 10 total; Girls:9 siblings,9 no siblings,18 total; Totals:13 siblings,15 no siblings) is the correct one.
