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. --------------------  |
