I know that the Birthday Paradox is the fact that in a room of 23 people, the chances are more than 50 percent that at least two people share a birthday. However, this is under the assumption that all the birthdays are equally likely. My question is, if there is some variability in the probability distribution of birthdays, will 23 people still be enough to get more than 50 percent? Note, I am not saying that 23 people will be the least such number, but simply that it is greater than or equal to the least such number for any possible probability distribution of birthdays.
