The Safe (Posted on 2003-08-11) Difficulty: 2 of 5
A group of crazy bank robbers try to crack a safe, even though they don't have a clue what the code is. The code has 5 numbers in, and the numbers on the dial range from 1 to 60. If they crack the safe, they get 100 billion.(That's a British billion - a million million). If they get the code wrong, they get caught and fined 1 million.

Assuming the bank robbers don't enter the same code twice, if they keep trying and re-trying until they crack the safe, are they more likely to have lost or gained money? If so, how much would they probably gain/lose?

correct me if i'm wrong | Comment 8 of 10 |
the number of different combinations is 777600000 i would then think that they would crack the code about half way through (although they could very well crack it on the first try or the last try) the codes thus it would still be a loss is this thinking correct ?
