As I read your post, I clearly see that it is written/created by unprofessional Math writer.
A professional Math writer will NEVER write " Two students will be independently selected at random ",
because in this context it is not an appropriate wording.
A normal Math writing for this situation is " Two students will be selected at random, with replacement ".
Assuming that the problem is modified accordingly, the solution is
P = 0.4*0.4 = 0.16. ANSWER
Solved, with my editing.
------------------------
What is written in the post by @lynnlo, it is impossible to understand or interpret.
So, simply ignore his post.
