Mathematical Oddities #7



One thought on “Mathematical Oddities #7

  1. In a room of 23 people it is more likely than not that two share the same birthday. The figure is just over 50%, but this runs totally against one’s tuition. I would assume that with 61 people the chance of two birthdays coinciding is very high, indeed may well be 99.5%, but I shall not bother to do the maths to verify this.

    As an oddity, did you know that Charles Darwin and Abraham Lincoln not only shared the same birthday, but were born in the same year? (Feb 12, 1809).
