Answer:
2 male students didn't visit six falgs.
Step-by-step explanation:
Hello!
You have the following information:
The class has 10 male students and 14 female students.
From the females, 8 visited six flags over Georgia.
And from the total of students of class 16 visited the six flags over Georgia.
Using this information you have to calculate the number of male students that did not visit six flags.
First step: Calculate the number of male students that visited six flags.
The total of students that visited is 16 from those 8 are female then 16 - 8 = 8 male students visited six flags.
Second step: Calculate the number of students that didn't visit it.
From the total of male students in the class, 8 visited six flags so 10 - 8 = 2 male students didn't visit six flags over GA.
I hope this helps!
