Ever notice when you go out to eat at a casual dining restaurant that it seems like everyone is having a birthday? I swear..... every 15 minutes I hear a song from the servers and some clapping. My older son once told me he faked having a birthday to get a free desert... how disappointed I was!!! Anyways..... what are the odds that someone in the dining room actually "has" a birthday? What are the odds that someone at work has the same birthday as me????
My is birthday- Nov 25 (if you want to know.... it occured on Thanksgiving several times as a child so I had very few parties...."sad face")
Now for the Puzzle....
I am in a meeting room with my coworkers Kelly, William, Alex, Patrick, Sue, Leigh, Joseph, Philip, Merlin, Jenny, Joshua, Janni, Rodney, Michael, Jon, Sarah, Amy, Kristin, and Carl waiting to eat cake for my birthday.
Right before I blow out my candles another 20 people I've never met enter from the next office to join in (aka- get free cake). What is the probability that anyone in the room shares the same birthday? Put the % in the format XX.XX% into the checker to obtain the coordinates to the final. Good luck! This puzzle requires no math!
