Hi phrontister;

Would you consent to starting a new thread for the new problem and putting back the old problem the way it was?

Hi Bobby,

I didn't keep a copy of the original, and besides, as it had holes in it that allowed for multiple solutions I'm not sure it should be resurrected. Can you track back to it?

I don't mind starting a new thread. It might be a good idea, anyway, seeing I got way off topic from your post #1629. Maybe all our off-topic to-ings and fro-ings re my puzzle could be deleted to tidy things back up.

Is that what your request is getting at?

Hi;

I can not move individual posts, the site does not support that. But your problem is good enough to start its own thread. So please do that.

I will recreate the old question in case someone wants to work on that.

Hi;

I have amended the problem, post #1644 so that there is the solutions we have discovered. It serves as a good warmup to your tougher problem.

Hi Bobby,

I've started the new thread for my puzzle...and I tried to express the wording more clearly, too (hope I succeeded!)

Thanks for helping to iron it out.

Yes, it was interesting.

For any one who is interested there are two outstanding problems at post #1629 and #1644. Try them!

**New problem:**

**A says) A person in town walked up to me and asked me a question that was puzzling them. They said there are 2555 people who live in town. When we checked the birth certificates we found that there were 5 days of 2011 that did not have a birthday for their town. **

**You mean 5 days did not have anyone born on those days with a population 2555! That is preposterous cried A, whomever did that tallying should be dismissed. As mayor I will do it myself, what is her name!**

**B says) Hold on A. There is almost a 25% chance of there being exactly 5 days with no birthday, hardly cause for dismissing someone. She might be correct in her count.**

**A says) There you go again, getting it all wrong B. I really think you should stick to whatever it is you used to do before you worked as mathematician. By the Dirichlet drawer principle there is slightly more than 7 birthdays for each of the 365 days. The odds are billions to one against there being 5 days with no birthday.**

**C says) A is right B. Did you really work on our country's defenses? No wonder we are slipping. You probably cost us Nam.**

**D says) Yes, B does look like a commie to me, let's take him out back and string him up.**

**E says) Hold on B is not a commie! It is A who should be hanged for continually misusing math. That explanation using the pigeonhole principle is about as bad as can be. B's estimate of 25% is pretty close.**

**A says) E, I do not think you know anything about probability or pigeons.**

**C says) Here, here! That is telling her. Let's get two ropes.**

**Looks bad for B and E, can you save them before A and his moonies lynch them?**
