Answer 2

Step-by-step explanation:

Let us consider that the student has to take 3 courses and he can take,

Mathematics at 8, 10, 11, 2’O Clock.

English at 9, 10, 1 or 2’O Clock.

History at 8, 11, 2, 3’O Clock.

We have to find the total number of ways in which he can schedule these three courses.

We know that a person can attend only one class at a particular time.

So we will solve this question by taking different possible cases.
