If you say that I asked you what the probability was, you can answer either .5 or 1, depending on when you believe my time reference dealt with.

 Posted: Fri Oct 29, 1999 7:11 am    Post subject: 5 On sunday I flipped some coins. If I flipped one coin, I'll only ask you on monday what the odds are that one coin came up heads. If I flipped two coins, I'll ask you on monday and tuesday what the odds are that one coin came up heads. You have a very bad memory, never know what day it is, and wont remember if you've been asked before. In fact, you'll barely remember the question that I just asked you, let alone something that happened many hours ago. Being a strong puzzler, how would you answer the question? What are the odds that one of the coins I flipped came up heads? Nick
