Answer 1

Answer:

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

Step-by-step 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
