As part of a class project, a university student surveyed students in the cafeteria to look for a relationship between the students' eye color and hair color. The table contains the survey results. Match the descriptions with the correct values.

Ok, so

If we analyze the tab, we notice the following things:

- The number of students with blue eyes and blond hair is 42. That's because if we go to the table and look at the rows and columns, 42 is the number which relations these two facts.

- The number of students with gray eyes and brown hair, is 5. That's because if we go to the table and look at the rows and columns, 5 is the number which relations these two facts.

- The difference of the number of students with gray eyes and brown hair and the number of students with green eyes and black hair is:

- Green eyes and black hair - gray eyes and brown hair

=> 11 - 5, which is 6.
