23 And Football Birthdays (2012x12)

Date de diffusion: Fév 14, 2012

What's the probability that two people on the football/soccer pitch share a birthday? That's only 23 people (22 players and the ref, as long as there have been no red cards or injuries!!!) and there are 365 days in a normal year. Dr James Grime explains. Our thanks to Nottingham Forest Football Club.
