(1) The subject asks if one of the sides is red and receives "yes". (2) The same is in original problem: "What is the probability that that card is the card with two red sides?"

The difference is that in the original problem the side of the card is chosen randomly while in my problem the card is chosen randomly. That changes problem's sample space.

Now I see what was my mistake. I was not taking into account that the card itself and what side is up are both choosen randomly. So, my reasoning would be correct if the problem was stated differently. "Three cards are placed into a hat. One card has a white face on both sides. A second card...

I am too lazy to do the math too but my estimations are different: a) about 1/3 b) about 2/3 c) about 1/3 d) 30! I am pretty sure that this problem has no similarities with "the same birthday" problem. There must be a lot of factorials involved in the solution of this problem. Because...

Yes, I saw this answer posted. However, since the problem was not carefully worded, it does not realy have a solution. You are talking about listed people and it is irrelevant. The problem is about people who have unlisted phone numbers. You assume that "to have unlisted phone number" is the...

Ogre, Ogres, Ogress and Needle, Needles, Needless seem to complete the list.

The answer to the question depends on what percentage of customers have delisted their numbers and what percentage of customers have discontinued their service since the data for the phonebook's last edition was compiled.

I did not take the offense anyway. I wonder what you meant then, though.

Putting aside intended insult, this statement is foolish and logically flawed. Moreover, you are evidently wrong. I did not see it then, but I see it now. However, that did not happen due to your input. I say "input" because I think that you post, which consisted of two parts, Ad Nauseam...

I am not a trader, so I do nothing. As a trader-wannabe, I give myself a little credit for admitting that I was wrong. I am also going to give it another thought trying to see where I was wrong which hopefully will help me better understand myself and the world around me.

Thanks, I can see that this is true. I still fail to see a mistake in my reasoning, though. :(

You said it twice. If you keep saying sugar, that does not make it any sweeter for me. And I think I clearly demonstrated that this can be achieved without changing conditions, ie tweaking the odds. This statement is a nonsense. First, we do not know how many red sides the card in the...

Mr Subliminal, that did not make it any more intuitive for me. If you are good at this, please reply with your comments to my previous post.

So true... Very often, isolating the problem by taking out parts (swapin, if you can) is the only way to go. One more thing to address. Since this looks like a hardware problem, get all the updates including BIOS and drivers.

I must admit, this sounds very convincing. However, I believe that solutions of this type are methodologically flawed and, as a result, incorrect. The fault, as I see it, is that you are taking into account events which took place in the past and I think that just brings a confusion into...

Of course it's 50%. It may seem like 66% is the probability to pick a red side out of three sides left, two reds and one white. However, you should not count one red side which is the other side of white/red card. That outcome is impossible because the side we see is red, not white and therefore...

I rest my case...

What I was saying is that a concept can be accepted by the majority of people even if nobody had "direct experience" with its subject, while you implied that "direct experience" is a must. Then why people think that the world is not flat? I think I devoted fair attention to your analogy...

If your arguments were true, then frequently people without a sense of smell would not believe in existnse of odors same as blind people would not believe in existnse of colors. That's hardly true. So, following that analogy, if God's existense was as verifiable as an existense of an odor, there...

What for? Arguing with your experience would be plain foolish because that would mean making an assumption that your perception is objective and correct while it is subjective and not necessarily correct. You are using that analogy second time which means you probably think there is some...
