    Non PWC Mathematical Question?

    Can someone tell me the total combinations (or odds of guessing the combo) of a 3 digit lock. The numbers used are 0-9 and the three digits do not repeat.

    Holdon, not doubting but just curious, what was the equation to get that number? Would it be 1000 if the numbers could repeat?

    I figured it out repeating would be 10 cubed. Non repeating would be 10x9x8.

    If they could repeat it would be: 1,000 10x1!x10x1!x10x1!=1000

    If they could not repeat, it would be: 720 10x1!x9x1!x8x1!=720

    3744 - 1 non sequencial. Random selection 1 of 11233.? Odds of you getting 1 no. with 3 digits.
