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?

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... |
