Yes, I do. The other day, I asked you about a difficult brain-teaser. Today, I also want to ask you another one. This one is quite difficult to me, as well:
How many people must you collect into a room before you have a better-than-even chance that two of them would have the same birthday?
I think, in an extreme cases, even if there are 365 people in a room, it could be possible that their birthday are all different. Therefore my answer is 365+365/2 = more tan 548 people. What do you think of that?

I got them from the autobiography "The Sky is Not the Limit" written by an astrophysicist, Neil deGrasse Tyson. He seems to be an extremely popular scientist in the USA. Well, I'm truly sorry. It may sound as if I were testing you. Actually, he gives the answer of the previous brain teaser without any explanation in the book. It's twenty-four. Truth be told, I'm totally confused now. Did I misinterpret the question?

According to ChatGPT, "Better than even chance" means that the probability of the event happening is greater than 50%, indicating a higher likelihood of it occurring. Now, thinking backwards from the answer: twenty-four, regarding birthdays, I would say that Tyson may only matter days and rule out the difference of a month. If that's the case, do 24 people take up over 50% of 30 days?

With all due respect, sir, I don't understand what you mean. How well does Tyson explain the matter? Concerning this brain teaser, all he says is just one sentence that I mentioned in #2.
