#0, birthday odds
Posted by Deborah Cox (Guest) on Jan-05-01 at 12:26 PM
Hello,

I would do like to have your help finding a solution for this little question.

I tried to find an answer in many sites, but without sucess.
It's a birthday odd question. What are the odds of a man meet a woman who shares the same DAY and HOUR of birth (ex. march 25th at 9:00 am). If you cannot help me with solving it, can you indicate a site that I should look up for?

Thanks for your attention,

debbie
They're not born at the same year.

Two people have a birthday on the same day with the probability of 1/365, and within the same hour with the probability 1/24. The answer to your question is the product 1/24 · 1/365.
