a teacher created two way table for four different classrooms the tables track whether each student has an after school job or not and whether they are in art class only, music class only, both classes, or neither class.

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
