You read on the internet that you can only get about 50 people in a room before it's almost certain that two of them will share the same birthday. You've decided to throw a party to test that theory. Start naming famous people, living or dead, and Alexa will keep track of their birthdays. How many guests will arrive at your party before the universal truth of math and probability takes over? As the party grows your guests will begin interacting with each other, so every game is exciting and new!
