Solution 1

1) Learn your lessons. We don't do homework.
2) Look here: http://nmap.org/book/images/hdr/MJB-TCP-Header-800x564.png[^]
3) This is incomplete. The header is at least 20 bytes long. You had given only 6. The first two questions can be answered (80; http), but for the third one, you need the rest of the header.

Well, consult with your tutor, or check the assignment again. You got your answer - I suggest you accept it.
