Strange how these "1 in 48,000,000" events keep on happening!

The Daily Mail has a story today about the Allali family whose third child was born on the same date as his two older siblings, claiming that "mathematical experts have revealed that the three siblings have beaten odds of 48 million to one". If these are the real odds, isn't a bit strange how often this story appears in the papers?

I am not sure who these mathematical experts are, but their error is pointed out in the comments following the story which correctly assess the odds as 1 in 133,000, assuming every birth day is equally likely. One of the correspondents makes the nice point that around 167,000 'third' children are born each year in this country, and so we would expect to see this story once or twice a year. See our article on a previous occurrence.
