There are a set of kids (N kids) asked to sit in a row of seats, leaving at least one empty seat between them until all seats are filled. At the end, how do I calculate mean of the fraction of occupied seats? What will be the input to calculate mean?

Thanks for the reply.

Here is my understanding. Let's say there are 30 seats and by leaving at least one seat empty, there will be 15 occupied seats. Since I need to calculate mean for the fraction of occupied seats, it will be mean for 1/30, 2/28... etc. Please correct my understanding.
