Hello I have an algorithm homework could you help me? Assume that there are 40 students in Prof. Caskurlus Computer Algorithms class and the classroom has exactly 40 seats. The students are all responsible and attend to all the classes so there are no empty seats during the lectures. There are two lectures per week, one on Monday and one on Thursday. Assume that for the Thursday lecture, the students enter the classroom one at a time, and each student entering the classroom selects an empty seat to sit uniformly at random from the set of available seats. What is the expected number of students that sit on the same seat both on Monday and Thursday?
