  • @john4556

    Im doing a variation of this problem where Pk is the probability that no two people share the same birthday, and I am supposed to show that it is maximized when all birthdays are equally likely. Which means that for any birthday i, Pi = 1/n where n is the number of possible birthdays. Anyone know how I should start going about this?

    • @john4556
      @john4556 Před 2 měsíci

      Because generally the problem has you assume that each birthday is equally likely in order to find the probability, but here I am simply supposed to prove that the probability is maximized under that assumption
