I'm bored, so I thought I'd annoy you with a mathematical puzzle...a nice simple one though.....
Monkeyfiend has 3 boxes: 1,2 & 3.
In one of the boxes is £1000000, the others contain something rubbish. You pick a box, say box No.1 and MonkeyFiend (who knows whats in each of the boxes), opens another box, say box 3, which contains a rubbish prize. Monkeyfiend then says do you want to pick box No.2 or stay with your original choice of box 1?
Which should you do and why?

ive seen 21 so i no the answer. i cant quite remember it tho
you stick with the one youve chosen, because the odds have changed (for you having the right box) to 66% because the one monkey opened has now been disgarded.

is fido's the real answer? cuz it sounds like it could be, but also you may have just worded the OP wrong.
plus if that's the answer.... URLAME

i doubt its the answer. it doesn't say if u saw what was in box 1 when u picked it the first time.

you havent seen inside the boxes yet, youve just picked one to be opened

nope the original is phrased corretly I believe: you pick a box (box 1), you don't see it's contents. I show you the contents of the 3rd box (which is rubbish) - so do you stay with your first choice (box 1) or change to the remaining box (box 2)

You punch monkey in the face, steal both boxes and tell him to stop playing homo mind games.
Only to find monkey put rubbish in all the boxes lol

mmm the original did not say you pick a box and don't see it's contents, it simply says monkeyfiend knows whats in all the boxes. it doesnt say you cant look before you give monkey your answer

Equally I didn't say the boxes explode into a rainbow of badgers - it's not damn word trickery, it a maths problem

You never said we acctually pick box, just that as an example we take box one, but now i know what is in box 3. So if I took box 3 when the real option came along, allowed you to open box 1 and realise there is rubbish in both, so i would then swap my box for box number two and get my money???????
Prob wront but its the only thing i can think off

((p=>q)&(q=>r))=>(p=>r) = +++++++++++++++++++++++++[>++>+++>++++>+++++<<<<-]+++++++++++++++++++++++++>>>>----.----------.++++++.<<<<+++++++.>>>---.>---.<++++.<<<.>>>++.------.>+++++++.<<<<+...
there is a 50% chance that the money is in box 1 so it doesn't matter which box you choose.
MonkeyFiend
Jan 31 2009, 01:39 PM
I just don't see how a uniform (t-suf) subsitution equation ((p=>q)&(q=>r))=>(p=>r) can possibly = that I am gay
50% is also wrong
=R6= Raile
Jan 31 2009, 01:52 PM
if it isn't some trickery of words.. and you think it's NOT 50%, then I guess it depends on how you look at it.
The second the box #3 is revealed, and you are given a second chance to pick the right box, the odds reset themselves. you then have a 1 in 2 chance of picking the right box...

cos the orange one isnt on top of the green one like it is above...
MonkeyFiend
Feb 6 2009, 10:50 AM
...but how can re-arranging the blocks of the same size produce a shape that's the same as the first one but with a 1cm block missing?
Surely if you're using the same blocks to form the same shape, then you can't have just lost some surface area?

might be easier to produce the answer in the following form....

I know, I know XD (Well, I think I do, one of the maths teachers in my school showed me this)
The hypotenuse of the red triangle (and maybe the green) isn't a straight line, it curves inwards slightly.
*Hopes a fool was not just made of herself*
Lawpf2001
Feb 6 2009, 01:16 PM
think your right. if you start at the top of the triangle go down 2 then left 3. look at the comparitive sizes of thse boxes
MonkeyFiend
Feb 6 2009, 01:21 PM
Good Work!
The answer is because it's not a triangle
The green triangle is slightly steeper than the red
Red triangle 3 high, 8 wide = 3/8 = .375
Green triangle 2 high, 5 wide = 2/5 = .400
Difference = .25

a man goes 2 market and buys a chicken,a fox and some grain.on the way back home he has 2 cross a river using a fallen tree.he can onlytake one item across at a time, how does he get them all saftely over 2 the other side clue:if he takes the fox over first the chicken will eat the grain

Feb 6 2009, 04:30 PM
The man takes the chicken over first from side A to side B, then the man takes the grain over from side A to side B, when leaving side B to reurn to A he takes the chicken back with him. Once back at side A he drops off the chicken and picks up the fox, takes the fox over to side B comes back for the chicken and takes it over the river.

and how many times do i visit?
MonkeyFiend
Feb 6 2009, 09:23 PM
when A and B are any (positive) number but both the same
I'll stick the number of visits for january up later
(if you have either or both numbers negative you and up with one half being -X and the other being +X)
