Hello - the birthday problem is interesting but it has no bearing on a simple percentage probability. The reason the odds of two people having the same birthday don’t rise linearly with the number of people is that every time you add someone to the set you also add a new possible birthday to match. You get to compare them to every other member of the group for a chance to match. You’re not just adding 1/365 each time, trying over and over to hit one date. You’re adding new dates to hit as you go.
This doesn’t apply in a simple probability like “0.6% of people have a micropenis so if you know 300 people, odds are you know one.” You really are just adding 0.6 every time you consider one more person in the set.
So… your comment is bullshit.
Damn must suck to be born without a sense of sarcasm.
Oh I was born with one of those. Also a bullshit detector, which is going off at your “I was joking” defense.
