Oh, dude, you're hitting me with some math now, huh? Okay, so if you have 5 digits to choose from for each of the 4 spots, that's like 5 choices for the first spot, 5 for the second, 5 for the third, and 5 for the fourth. So, it's like 5 x 5 x 5 x 5, which equals 625 possible 4-digit combinations. Math can be fun, right?
It can be calculated as factorial 44! = 4x3x2x1= 60
To find the number of 3-digit combinations using the digits 0 to 9 with repetition allowed, we consider that each digit can be any of the 10 digits (0-9). Since there are 3 positions in the combination, the total number of combinations is calculated as (10 \times 10 \times 10), which equals 1,000. Therefore, there are 1,000 possible 3-digit combinations.
The total number of possible lock combinations depends on the number of digits and the range of each digit. For a standard 3-digit lock using numbers 0-9, there are 10 options for each digit, resulting in 1,000 possible combinations (000 to 999). If the lock has a different number of digits or uses letters, the calculation would vary accordingly. For example, a 4-digit lock would have 10,000 combinations.
A 4-digit code using the digits 0-9 can have each digit independently chosen from 10 options (0 through 9). Since there are 4 digits, the total number of combinations is calculated as (10^4), which equals 10,000. Therefore, there are 10,000 possible combinations for a 4-digit code.

Possible 5 digit combinations using 5 digits only 1 time is 5! or 5*4*3*2*1 or 120. Using 5 digits where numbers can be used 5 times is 55 or 3125.
If the digits can repeat, then there are 256 possible combinations. If they can't repeat, then there are 24 possibilities.

With repeating digits, there are 33 = 27 possible combinations.Without repeating any digits, there are 6 combinations:357375537573735753
The order of the digits in a combination does not matter. So 123 is the same as 132 or 312 etc. There are 10 combinations using just one of the digits (3 times). There are 90 combinations using 2 digits (1 once and 1 twice). There are 120 combinations using three different digit. 220 in all.
To calculate the number of 4-digit combinations using the digits 1, 3, 5, and 7 exactly once each, we can use the permutation formula. There are 4 choices for the first digit, 3 choices for the second digit, 2 choices for the third digit, and 1 choice for the fourth digit. Therefore, the total number of combinations is 4 x 3 x 2 x 1 = 24. So, there are 24 possible 4-digit combinations using the digits 1, 3, 5, and 7 exactly once each.
120 combinations using each digit once per combination. There are 625 combinations if you can repeat the digits.
