In a room of 23 people there’s a 50% chance of two individuals having the same birthday (month and day only and not a leap year). The chance increases to 99.9% if there are 70 people in the room. You need at least 253 people in the room if you want someone to have the same birthday as you with 50% probability. This is called the birthday paradox or birthday problem. Try it out on your classroom, office, or sports team and confirm how many people share the same birthday.
