The missing number in the table is 19.
To find this missing number, we can use the total values given in the rows and columns.
Total number of students who like dance = 42
Total number of students who do not like dance = 26
Total number of students who like music = 38
Total number of students who do not like music = 30
Since the total number of students who like music and dance is 42 (from the row), and we already know that 23 students like music and dance, we can calculate the missing number by subtracting 23 from 42.
42 (total students who like dance) - 23 (students who like both music and dance) = 19
Therefore, the missing number in the table is 19.
