Birthday paradox

flaming_cake Apparently, "In probability theory, the birthday paradox states that given a group of 23 (or more) randomly chosen people, the probability is more than 50% that at least two of them will have the same birthday. For 60 or more people, the probability is greater than 99%, although it cannot actually be 100% unless there are at least 366 people."

Well, I have news for the probability theorists. If you gather together all the surviving members of my immediate family - that's all two of us - it's already 100%, as we both have the same birthday. What was the probability of that? 

Definitely the birthday problem though, is that it's today and I am having one of those horrible milestone birthdays. You know, one of those with a big, fat ZERO on the end, which of course has no value whatsoever, but still gets taken into account. It's grossly unfair! While mother insists on being "selectively dyslexic" and claims to be 38 today, there won't be any candles on my cake, because the nearest fire station is much too far away from here!
