Final answer:
To find the number of students who do not watch a TV program regularly in a class of 48 students where 1/4 watch the program, subtract the number who watch (12) from the total (48). This yields 36 students.
Step-by-step explanation:
If 1/4 of the 48 students watch a particular TV program, we would first find out how many students watch the program. To do this, multiply 1/4 times 48 which will yield 12. This means, 12 students regularly watch the TV program.
The question requires us to find the number of students who do not watch the TV program regularly. To find this, subtract the number of students who watch the TV program from the total number of students, that is, 48 - 12 = 36. So, 36 students in the class do not watch the program regularly.
