I'll do the first one:
Both novels.

Student 1 picks a novel. There are 3 novels out of 6 books total.

Now there are 5 books left.

Student 2 picks a novel. There are 2 novels out of 5 books since the other student took a novel.

To find the probability you would multiply the probability student 1 gets a novel and the probability student 2 gets a novel.

[tex] \frac{3 Novels}{6 Books} x \frac{2 Novels}{5 Books} = \frac{6}{30} = \frac{1}{5} [/tex]

So the probability is 1/5. Or 20%
