Answer 1

Classes studied for, Classes he did not study for Total

Classes Passed, 23 4 27

Classes Failed, 3 2 5

Total, 26, 6 32

Please find attached the two way frequency table formatted on Excel spreadsheet

Explanation:

The given information are;

The total number of classes Romain took in high school = 32

The number of classes he studied for but did not pass = 3

The total number of classes Romain passed = 27

The number of classes Romain studied for = 26

Therefore;

The number of classes Romain studied for and passed = 26 - 3 = 23

The total number of classes Romain failed = 32 - 27 = 5

The total number of classes Romain passed but did not study for = 27 - (26 - 3) = 4

The number of classes Romain did not study for and failed = 5 - 3 = 2

The total number of classes Romain did not study for = 4 + 2 = 6
