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 tongue.gif

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.

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

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) = +++++++++++++++++++++++++[>++>+++>++++>+++++<<<<-]+++++++++++++++++++++++++>>>>----.----------.++++++.<<<<+++++++.>>>---.>---.<++++.<<<.>>>++.------.>+++++++.<<<<+... tongue.gif

there is a 50% chance that the money is in box 1 so it doesn't matter which box you choose.

I just don't see how a uniform (t-suf) subsitution equation ((p=>q)&(q=>r))=>(p=>r) can possibly = that I am gay tongue.gif

50% is also wrong tongue.gif

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...
