Scheduling Eight Talks
Problem
Eleven students volunteer as museum guides. From 9 am to 5 pm there is one talk each hour ( talks in total), and each talk needs exactly one student speaker. To avoid fatigue, no student gives two consecutive talks, and the first and last talks must be given by two different students. In how many ways can the talks be assigned?
