Wrong on all accounts. In a group of 30 people, assuming birthdays are distributed equally through the year (which they aren't) chances of 1 birthday being shared by at least 2 of them is ~70%. In a group of 23, the chance is ~23%.
However, the chance of someone in a group of 30 sharing
your specific birthday is obviously far smaller.

I was just reading about this, its pretty cool. It basically explains about odds and stuff, for example, did you know that there are around 16 million other people on the planet that share the same birthday as you? When you're in Vegas, and you're at the hotel with say 50,000 other people, there will be about 134 people with the same birthday as you. Unless of course you're born on leap year, then there will only be like 34 people with the same birthday. Anyway, this shit is pretty interesting. Now I have something else interesting for you, I am going to sleep.

Wrong. There are seasonal variations, so some birthdays are less common than others.
