I am trying to find the expected value of the number of days where exactly $k$ people have a birthday in a class which consists of $60$ independently chosen people.
For $k = 0, 1, 2, 3, 4$
I am confused if the answer here is similar to the answer to this post, as here we need the expected value of the days not people?
And does the term "independently chosen" imply that I also need to apply a probability of choosing a certain person from the 60 ppl or is it just an indication to get the product of the events?
Any hints greatly appreciated
