All the possible digits (10 of them; 0-9) are multiplied by themselves by the number of digits that can be shown in the lock. (3) This is 103, or 1,000. This certainly shows why guessing is not a good way to break into a numerical lock, especially since three is a rather low number of digits for one!

6,720 combinations.

In most 3-number locks, each number ring offers a choice of 10 digits, from 0 to 9. I that case, there are 103 = 1000 combinations.

Assuming the digits cannot be repeated, there are 7 combinations with 1 digit, 21 combinations with 2 digits, 35 combinations with 3 digits, 35 combinations with 4 digits, 21 combinations with 5 digits, 7 combinations with 6 digits and 1 combinations with 7 digits. That makes a total of 2^7 - 1 = 127: too many for me to list. If digits can be repeated, there are infinitely many combinations.

If the 6 digits can be repeated, there are 1296 different combinations. If you cannot repeat digits in the combination there are 360 different combinations. * * * * * No. That is the number of PERMUTATIONS, not COMBINATIONS. If you have 6 different digits, you can make only 15 4-digit combinations from them.

5040, assuming none of the digits are the same. (Assuming they're not, there's 5040 unique combinations you can make out of 7 digits).

6 for 3-digits, 6 for 2-digits, 3 for 1-digits, and 15 for all of the combinations

There are too many combinations to list. There are 10*10*10 = 1000 combinations of numbers. ------------------------------------------------------------------------------------------------------------------ The combinations are simply the numbers 0-999 with leading zeros, e.g. 000, 001, 002,..., 099, 100, 101,102,..., 997, 998, 999.

Since a number can have infinitely many digits, there are infinitely many possible combinations.

10,000.

10000

There is only one combination. The order of the digits in combinations makes no difference. They are considered as being different if they are permutations, not combinations.

If you allow the combination comprising no digits, then 2^16 = 65536.

10x9x9x9

I would have to say 10,000 possible combinations. (0000, 0001, 0002 through 9998, 9999)

45 In combinations, the order of the digits does not matter so that 12 and 21 are considered the same.

Allowing repetitions, there are 9 combinations. Without repeated digits, there is only one combination of 3 digits from 3.

about 1,0000000000000

Just one.

1000

Yuo can make only one combination of 30 digits using 30 digits.

With 4 digits you can have 24 = 16 combinations. 1 combination with 0 digits; 4 combinations with 1 digit: 1, 2, 4 and 8 6 combinations with 2 digits: 12, 14, 18, 24, 28 and 48 4 combinations with 3 digits: 124, 128, 148 and 248 1 combination with all 4 digits. In a combination the order of digits is not relevant so that 124 is the same as 142.

There are infinite combinations that can make 3879

There are 167960 9 digits combinations between numbers 1 and 20.
