Ashelf holds 3 novels, 2 biographies, and 1 history book. two students in turns choose a book at random. what is the probability of that the students choose each of the following?

1. both novels
2.both biographies
3. a history, then a novel
4. both history books

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.



So the probability is 1/5. Or 20%

(A) ASA

Step-by-step explanation:

They have the same two angles and the same side between so it’s the ASA (Angle-Side-Angle) postulate.

Hope that helps!
