To calculate the total number of possible 4-digit codes using the numbers 1, 2, and 3, we can use the fundamental principle of counting. Since we have 3 choices for each digit and we are choosing 4 digits, the total number of possible codes is 3 x 3 x 3 x 3 = 81. Therefore, there are 81 possible 4-digit codes that can be formed using the numbers 1, 2, and 3.
Since you've only given us 3 digits to put in 4 places, we have to assume
that it's OK to use the same digit more than once in a code. So we're also
going to assume that there's no limit on repetition.
The first digit can be any one of 3. For each one . . .
The second digit can be any one of 3. For each one . . .
The third digit can be any one of 3. For each one . . .
The fourth digit can be any one of 3.
Total possibilities = 3 x 3 x 3 x 3 = 81 possible codes.

How many possible 4 digit combinations are there using 0-9. how many different combination codes are possible?
There are 210 4 digit combinations and 5040 different 4 digit codes.
What are all the possible 4 digit codes using the numbers 0 to 9 without using the same digit twice in each code?
Any 4 from 10 in any order = 10 x 9 x 8 x 7 = 5040
How many possible 3 digit numbers can be made using the digits 604?
There are 4 possible numbers if the digits are not repeated; 18 if they are. Those are 3-digit numbers, assuming that zero would not be a leading digit. If zero is allowed for a leading digit, then you can have 6 for the non repeated, and 27 if repetition.
How many 3-digit codes using digits 0 through 9 are possible if repetitions are allowed?
10,000
What are all the possible 4 digit codes using the numbers 1-4?
There are 256. Some of them are: 1111, 1112, 1113, 1114, 1121, ... 2111, 2112, 2113, ... 3111, 3112, ... 4111, etc.

There are 210 4 digit combinations and 5040 different 4 digit codes.
What are all the possible 5 digit codes using the numbers 0-9?
There are 10000 such codes. Each of the numbers 0-9 can be in the first position. With each such first digit, each of the numbers 0-9 can be in the second position. With each such pair of the first two digits, each of the numbers 0-9 can be in the third position. etc.
What are all the possible 4 digit codes using the numbers 0 to 9 without using the same digit twice in each code?
Any 4 from 10 in any order = 10 x 9 x 8 x 7 = 5040

What are all the possible 4 digits codes using the numbers 0 9?
The possible 4 digit codes using the numbers 0-9 are every number between 0 and 9999. For numbers that have less than 4 digits, just precede the number with 0's. 10,000 possibilities
What are all possible three digit numbers using numbers 0-1-2-3-4-5-6-7-8-9?
Total number of possible 3-digit numbers = 9!x10!10!
