Adding one more person adds more than one comparison. Assuming birthdays are evenly distributed (they aren’t), 2 people have a 1/365.25 chance of sharing a birthday. But adding a third person adds 2 more chances. Adding that 23rd person adds 22 more chances than adding the 22nd person. 1+2+3…+22=253 separate checks, of which only one needs to match.

So does this apply to the problem: 0.6% of people have micropenis. How many friends do you need to have before you’ll know someone?
It doesn’t seem to, because there isn’t any element of comparing them between each other. It’s just a straight percentage chance.
No I was making a joke and everyone decided they were gonna do a full autism about it
