Answer:
24 ways.
Step-by-step explanation:
In this case, you just need a factorial.
For the first seat, you have 4 students you can place.
For the second seat, you have 3 students.
For the third, you have 2.
For the fourth, you have 1.
So, you can arrange the students by doing 4 * 3 * 2 * 1 = 12 * 2 = 24 ways.
Hope this helps!
