A college library has four copies of a certain book.The copies are numbered 1, 2, 3, and 4. Two ofthese books are selected at random. The first selectedbook is placed on 2-hour reserve, and the secondbook can be checked out overnight.a. Construct a tree diagram to display the 12 out-comes in the sample space.b. Let A denote the event that at least one of thebooks selected is an even-numbered copy. Whatoutcomes are in A?c. Suppose that copies 1 and 2 are hardcover books,whereas copies 3 and 4 are softcover books. LetB denote the event that exactly one of the copiesselected is a hardcover book. What outcomes arecontained in B?
