Engineer- OR, Mathematician test
To tell whether a person is an engineer, or a mathematics/ Operations Reasearch
type, give them the following problem: A box contained 50 red socks and 50 green socks. You withdrew two socks; one green and one red. What is the probability of having a matching pair on the next withdrawal? |

You withdrew two socks; one green and one red. What is the probability of having a matching pair on the next withdrawal? The question is too vague to generate a unique correct answer. On the second draw, do you toss the original two socks and draw another pair? Or you do draw one additional sock to add to the current set, from which you try to make a matched pair? Pretty much ousted myself with that response... |

... Please provide me your understanding of the term "matching pair". In what soical context do you utilize "matching pair". Etc. etc. until a thesis has been produced. You already have a matching pair of socks. (the red/green colorblind response) Sniff them. If they don't smell too bad, you have a matching pair of socks.

You allready have a pair that's close enough -why bother reaching in again.

"Lat705" wrote in message ... To tell whether a person is an engineer, or a mathematics/ Operations Reasearch Assuming the red socks are all identical to each other, and the green socks are all identical to each other, then your next withdrawal will give you a pair. This is a certainty, not a probability. Much more interesting is if you withdraw two green socks to start with, what is the probability of getting a pair on the next withdrawal? Or even, if you reach into an unknown sock drawer at random, what is the probability of withdrawing a dildo? Sock it to me baby! TL MC |
Engineer- OR, Mathematician test
An engineer, to vent his spleen,
got some socks in red and green, he placed them in a simple box, and proceeded then to withdraw socks. The first sock he withdrew was red, at which he frowned and scratched his head, taking up his old slide rule, he calculated long and cool, Finally he made advances, at working out withdrawal chances, a green sock he then brought to light, he calculated long, all night. At last he dipped into the drawer, and groped around for just one more, but he could not prove his theory, for it had got to dark to see, Disillusioned, baffled, beat, he placed two odd socks on his feet, nobody noticed his odd way, for socks at night, like cats, are grey. An engineer or mathematician, should stick to calculating fission, for calcuilating socks is sad. the results may turn out to be bad. Should you wish to avoid his plight, slide-ruling about all night, then just ignore this colour cack, make sure all your socks are black! TL MC |

Kevin notes:
You don't have to be using an algebraic formula to be thinking mathematically, you know. guilty as charged, Kevin. It is essentially a matter of statistics/probability, hence math. I was making light of my depth of thought, as I used simple logic(and a few assumptions).IE: if one has a red and green sock, any withdrawal creates a matched pair. Kevin, fighting mathematical ignorance for over 20 years (it's taking a lot longer than I had hoped.) don't worry, you will get better if you work at it.g Shoot, I've been fighting ignorance my whole life, but it still wins more than I do.

That's certainly a defensible POV; but as I read it, that is not the question. Lou's question states, "You withdrew two socks," thus defining a withdrawal as being two socks. The clear implication is that the next two socks withdrawn need to be a matching pair to satisfy the requirement. If that is not the intent of the question, then the question is poorly stated and Stan's answer is correct. Joe F. |

How does one define withdrawal, someone was heard to say,
how does one define a box? or even socks? as ask you may, How does one define a pair? or even green? or red? all these things depend on folk, understanding what you said. Engineering or mathematics are not the problem here, no matter what you write, for some it wont be clear, some will misinterpret, or simply fail to understand, and some will be insulted, and get quite underhand. ROFF is very similar to a box of coloured socks, but the colours here are infinite, which understanding blocks, no matter how you grope around, you will not find a pair, a basic sensible consensus is quite simply just not there. Some socks may be black and white, indeed just like some feet, and trying to make them change to red, is asking for defeat, just when you think you know the colours, even down to grades, a sock reacts most violently, and changes all the shades. So what to do you ask? This colour changing is not fair, quite right, the best approach I think, is to wear your colour bare, you do not have to show it, in fact it may be best concealed, if nobody changes shades at all, then all may be revealed. Of course one must be careful, and needs some perserverance, for ROFFians, like socks, are hard to judge by their appearance. Even what they write on here, may seem to some, arcane, in many cases changing shades, may cause some people pain. Unfortunately the day may come, when all the socks are grey, the red one´s and the green one´s, even purple, stay away, If you like the variations, need some colour in your life, accept the socks for what they are, this will save you strife. Choose your socks with care, and not by blindly groping, look for clean and pleasant socks, all the time still hoping, that you don´t get a nasty sock, which causes you to moan and shout, Until at last it is discarded, all smelly and worn out.
