My high school mate shares his birthday with his daughter.
I reckon Pie knows this already, but ... how many people do you think you would need in a group to give a 50% or more chance that two people share a birthday?

I completely suck at math. Like, my math could suck a trigonometry textbook through 50 feet of garden hose. But I guess at the most extreme you'd need 366 people to assure that there would be one duplicate birthday. (excluding a Feb29th)
But, and this is a complete I suck at math guess, if you only needed a 50/50 chance, couldn't you divide 366 by 2 and get something like 183?
But again, while I rock at geometry which isn't really math, I had to take college algebra three times to get a D.
Did I mention I suck at math?
