The conditional relative frequency of rows:
It is the relative frequency corresponding to each row.
It is obtained when we divide each entry of each row by it's corresponding row total.
It is given that:
This means that the sum of the first column i.e. who learn German is: 72
and first entry of first row is: 54
Hence, first entry of second row is: 72-54=18
This means that the second entry of first row is: 12
This means that the second entry of second row is: 10.
The FIRST TABLE is the answer.
