I would not like a list all possible 4 digit combination using 0-9.
i would like a list all possible 4 digit combination using 0-9
There are 210 4 digit combinations and 5040 different 4 digit codes.
There are 10 possible options for each digit in a 4-digit combination (0-9). Therefore, the total number of possible 4-digit numeric combinations using 0-9 is calculated as 10^4, which equals 10,000. This includes combinations such as 0000, 0001, 0002, all the way up to 9999.
1 is a single digit, 0 is the absence of a digit.

You should try out all of the three-digit combination. There are 10x10x10 = 1,000 possible combination (assuming digits 0-10).
yes.0 is a digit because if 0 is in 10,why wouldn`t 0 be a digit.
The question is incorrect since there are 210 - 1 possible combinations. The digit 0 can be in the combination or out. That gives 2 ways. With each, the digit 1 can be in the combination or out - 2*2 = 22 ways. With each, the digit 2 can be in the combination or out = 23 ways. With each, the digit 3 can be in the combination or out = 24 ways. etc. So 210 ways in all except that one of them is the null combination. Now 210 = 1024 so there are only 1023 combinations. If, instead, you allow the digits to be used many times, there is no limit to the number of combinations.
10x9x9x9
0 is a digit
That would be all the numbers that end with 0 or 5. So:* For the first digit, you have 9 options (digits 0-9). * For the second digit, you have 10 options. * For the third digit, you have 10 options. * For the fourth digit, you have 2 options (the digits 0 or 5). You can multiply all those together.
No, there are 1000 of them and I have better things to do with my life!
If the digit 0 is allowed then the answer is 1/(10*9*8) = 1/720 = 0.0014 approx. If 0 is disallowed, then 1/(9*8*7) = 1/504 = 0.0020 approx.
There are the digits 1 through 9 for the first digit. Then, we have 0 through 9 for the second digit - excluding the first digit. For the third digit, we have 0 through 9 excluding the two previous digits
