Homework 20

Details

1. (5) AIDM Problem 6.14 (Page 300). The final answer will be very simple!
2. (5) AIDM Problem 6.22 (Page 301). If you use the proper result from the book, this one is very easy. It does require using a few words, though!
3. (5) AIDM Problem 6.26(g) (Page 302). This one requires inclusion-exclusion. You do not need to determine the final number—an answer like \(12^5*\binom{12}{5}+ 12*11*10-\binom{7}{5}\) is acceptable (although the real answer is a lot longer than this!). Make sure to explain/show your logic.
