  • If what you want are all possible three digit numbers then you have 10 choices for the first digit, you have 10 choices for the 2nd digit,and you have 10 choices for the 3rd digit giving you
  •  10x10x10 = 1000 in all.
  • If what you want are all possible three digit numbers with no repetition of the digits then you have 10 choices for the first digit, you have 9 choices for the 2nd digit, and you have 8 choices for the 3rd digit giving you
  • 10x9x8 = 720 in all.
  • If what you actually want is  - combinations - that's something quite different. It is the number of ways to choose 3 of the 10 digits in which order is not important. There are 6 = 3x2x1 ways to order 3 digits in a row.  the number of combinations of 3 of the 10 digits is 720/6 = 120 combinations.
  • Its funny how every combination lock requires you to put the numbers into the lock in a particular order.  Perhaps they should have called it a permutation lock instead! lol

     You are right Thoth ! That's exactly correct.... it would be a permutation not combination. LOL 

      Hey look at this ..... I think they are saying you can get the first combination   permutation  number using our " MIRROR numbers" LOL   Check it out.... add 5 digits to the number. LOL

     HOW TO OPEN A MASTER COMBINATION LOCK

    How do you get those Master combination locks open when you've
    lost the combination? I found this file on a BBS and re-edited it to
    make sense
    . There was no reference to an author, so he will remain
    forever unknown.

    The Master Lock Company has made this kind of lock with a built
    in protection device
    . When you pull the shank of the lock (the part
    that springs open when you have given the lock the correct
    combination), the combination dial will not turn. That failure to
    rotate provides the key to being able to open a Master combination
    lock once you have forgotten the combination (something we are all
    prone to do!). There are three (3) numbers to a Master combination
    lock. You might want to get out a lock to understand easier.

    To determine the first number:

    Grasp the shank and gently pull on it. Do not pull it too hard
    or the dial will not turn at all! While pulling on the shank, rotate
    the dial to the LEFT until it will not rotate any further. Read the
    number under the index. Add 5 to this number and you have determined
    the first of the three numbers.

    To determine the second number:

    Relax the pressure on the shank and turn the dial completely
    around three to four times to the left. Rotate the dial to the right
    to the first number you determined. Then rotate the dial further to
    the right, bypassing the number once
    . When you have bypassed your
    first number, again gently begin pulling the shank and continue
    rotating the dial. It will eventually fall into a "groove" and the
    dial will cease to rotate
    . While in the groove, pull on shank and
    turn the dial. If the dial is lose and feels sloppy, go to the next
    groove
    . If the know will not rotate at all then you have determined
    the second number.

    To determine the third number:

    After getting the second number, relax the pressure on the shank
    and re-spin the dial. Then enter the first two numbers. After the
    second number, go to the right and at all the numbers give the handle
    a pull. The lock will eventually open if you did it right. If you
    can't do it the first time, be patient. Lock picking is not learned
    overnight and it takes time
    .

     Have a couple of locks around the house I don't know the combinations to, so...., easy getting the first number. Haven't got the second one yet 

    But this being lottery discussions, I was thinking....what if there were locks that only had 0-9 on the dial, not 0-30. Would be a heck of a basis to work a system out on, maybe that would be a good approach, to think of the pick 3 that way.

    Just a thought.
