Answer to my last blog (random room) ....

Wednesday, January 16, 2013

And, my patient friends the answer is as follows ...

99% probability is reached with just 57 people, and 50% probability with 23 people. These conclusions are based on the assumption that each day of the year (except February 29) is equally probable for a birthday.


It's a lesser number than I first guessed when asked - just another one of life's interesting quirks emoticon

    I used to love probability in Math class! (yes, I know - GEEK!)
What would it take for THREE people to share the same birthday?
On my Dad's road three of them all share the same day in February!
Hope you are starting to feel better....I lost my best friend last year
and I still think of her every day. GOT TO SHARE THE SPARK!!! emoticon

    LOL! I read your blog yesterday and gave up. I never would have figured that out. I almost caved and asked my Boss. No one said there would be math involved here:)
Take care and be good to yourself.

    Lol while I understand the math behind it all, the bottom line is still that it would only take 2 people in a room to have 2 people with the same birthday. :)

I love brain teasers though - thanks for sharing!
