7. A bookshelf has 12 computer science textbooks. The lecturer is concerned about the coverage of the topics of A* Search (A), Binary Search Tree (B) and C++ (C) on those specific books. After scrutinizing the books, it was found that |B| = 13 |C| = 13 |A| = 8 |An B| = 5 |Bn C| = 6 a. How many of the books contain material on exactly one of the topics? |An C| = 3 |AnBnC| = 2 b. How many do not have any of the topics? c. How many contain material on only A* Search and Binary Search Tree?
