I had a birthday problem question that I'm really interested in knowing the answer for:
In a group of 2,000 people, what is the probability of one day during the year that no one has that particular day of birth? What about the probability of having 10 days not having a birthday within them?
For the real life story, I work for a company which we have just discovered that there are 10 particular days which no one has a birthday on. We thought it strange, but we were wondering if this was actually an expected outcome. I didn't know where else to turn. Thanks in advance for your input!
