Nice! I never heard of that. From a different website...
http://www.dailymail.co.uk/news/art...pervisors-eggs-beat-odds-QUINTILLION-one.html
Only one in every 1,000 eggs produced in this country is double-yolked, so the chances of getting even six in a row are 1,000 to the power of six –or one quintillion– roughly the same odds as winning the Lottery three times
That quote is from a different country but I would guess the odds are pretty close. So...odds for two would be 1,000 to the power of two (squared - or times 2). One in a million.
