Re: Another coin problemThe sun sign is the position of the sun at birth. The rising sign is calculated from the hour. At least as far as I know. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #52 20130327 23:40:08
Re: Another coin problemOkay maybe its the rising sign then.., 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Another coin problemThe 24 hours are divided into 2 hour periods and your rising sign is computed from there. In mathematics, you don't understand things. You just get used to them.

Re: Another coin problemSpeaking of, my prof. recently asked us to search up a proof for the Linearity of Expectation function which I just found. I have discovered a truly marvellous signature, which this margin is too narrow to contain. Fermat Give me a lever long enough and a fulcrum on which to place it, and I shall move the world. Archimedes Young man, in mathematics you don't understand things. You just get used to them.  Neumann #55 20130327 23:58:06
Re: Another coin problemI would like to see that. 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Another coin problemThe linearity of expectation is surprising because there is no need for independence. In mathematics, you don't understand things. You just get used to them.

Re: Another coin problemIs the answer of the first 0.25*0.25*51?? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Another coin problemWhy? Whats wrong? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Another coin problemThe probability that the second card is the same suit given the first is 12 / 51. In mathematics, you don't understand things. You just get used to them.

Re: Another coin problemI would say the answer to the first one is 12. The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #64 20130328 01:19:30
Re: Another coin problemThat is what I am getting too. Of course it is a bad answer! In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #65 20130328 01:21:54
Re: Another coin problemActually, shouldn't it be 11?

Re: Another coin problemWhy do you think so? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #67 20130328 01:33:29
Re: Another coin problemNo, sorry. I forgot there were 13 cards in a suit.

Re: Another coin problemI did not say it is wrong. It is correct but it is still a bad answer. Sufficient for the people on forums but not sufficient for real work! In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Another coin problemEver seen the way these guys work? Ever checked any of their answers? Conjectures that they never even try a single example against... In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #71 20130328 01:58:23
Re: Another coin problemUhhuh. Ok, then we can also use a simulation to confirm the answer.

Re: Another coin problemAlready did that, got 12.0004. Now I can hand the answer into my boss and get paid the big bucks. In mathematics, you don't understand things. You just get used to them.

Re: Another coin problemSeveral of them in the past. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #75 20130328 02:48:19
