Why the word combinations? |
2004-05-05 |

From Megan:
Why are locker combinations called locker combinations not locker permutations. The order of the numbers matter so why aren't they called locker permutations.

Combination locks |
2002-08-17 |
|
From John:
How many combinations of three number codes can occur with a standard combination lock? The range of possible numbers is 0-39 which allows 40 different possible choices each turn of the dial. Each combination requires exactly three numbers (i.e. three turns of the dial). E.g. 35-40-5. Allow for reuse of the same number three times e.g.10-10-10. I don't think there is any preference shown for certain number combinations. Can you explain how the total is derived? Someone at the YMCA this week put this question to me and I gave an answer but I am not sure I am right--so I have come to you.
