The missing number in the table is 19.
To find out, we can use the fact that the total number of students who like music is 38, and the number who like both music and dance is 23. Thus, the number who like music but not dance is 38 - 23 = 15.
Similarly, we know that the total number of students who like dance is 42, and the number who like both music and dance is 23. Therefore, the number who like dance but not music is 42 - 23 = 19.
