### Re: 2 puppies

Yeah, you guys are right. I should have phrased that as:
"Yes, the first dog I received is male, I did not check the second yet."

Edit: Argh, and as Ermes notes, it would still depend on the storekeeper's behavior.

### Re: 2 puppies

I'm probably just being stupid, but I can't get past thinking that as the sex of one of the puppies is given, the probability would still be 0.5 If you examine it this way, where x = Pr(the puppy which the owner confirmed to be male, is male) and y = Pr(the other puppy, who's gender...

I think some people (gladly, not most here) are making a logical error. A -> C, and B -> C, doesn't mean that A = B.

### Re: Inconsistent variables in the two envelopes problem

A coin-flip or other fair random process (50/50 odds) determines which envelope you open. You see an amount A. Now you know either A=L or A=2L , but you don't know the probabilities of these. So your expected value from the envelope you opened is clearly A. Your expected value from the other envelo...

If it is impossible to design a system that never loses data, how can you treat an opt-out as permanent? How does one identify that they are not an organ donor? Do they carry a card?
