Oh, dude, you're really into numbers, huh? Well, if you want to know all the 4-digit combinations you can make from 1, 2, 3, and 9, it's like this: 1239, 1293, 1329, 1392, 1923, 1932, 2139, 2193, 2319, 2391, 2913, 2931, 3129, 3192, 3219, 3291, 3912, 3921, 9123, 9132, 9213, 9231, 9312, 9321. Hope that satisfies your number-crunching cravings!
This question needs clarificatioh. There are 4 one digit number combinations, 16 two digit combinations, ... 4 raised to the n power for n digit combinations.
There are 840 4-digit combinations without repeating any digit in the combinations.
To calculate the number of different 4-digit combinations that can be made using numbers 0 through 9, we use the concept of permutations. Since repetition is allowed, we use the formula for permutations with repetition, which is n^r, where n is the number of options for each digit (10 in this case) and r is the number of digits (4 in this case). Therefore, the number of different 4-digit combinations that can be made using numbers 0 through 9 is 10^4, which equals 10,000 combinations.
There are 210 4 digit combinations and 5040 different 4 digit codes.
9,000 - all the numbers between 1,000 and 9,999 inclusive. * * * * * NO. Those are PERMUTATIONS, not COMBINATIONS. Also, the question specified 4 digit combinations using 4 digits. The above answer uses 10 digits. If you start with 4 digits, you can make only 1 combination.
120 combinations using each digit once per combination. There are 625 combinations if you can repeat the digits.

"There are 10,000 different combinations"-Hey nick! love dave and jalp

The answer is 10C4 = 10!/[4!*6!] = 210
To calculate the number of different 4-digit combinations that can be made using numbers 0 through 9, we use the concept of permutations.

Therefore, the number of different 4-digit combinations that can be made using numbers 0 through 9 is 10^4, which equals 10,000 combinations.
A 4-digit number can range from 0000 to 9999, which includes all combinations of four digits. Since each digit can be any number from 0 to 9 (10 options), the total number of combinations is calculated as (10^4). Therefore, there are 10,000 different combinations for a 4-digit number.
Each digit can appear in each of the 4 positions. There are 9 digits, therefore there are 9⁴ = 6561 such combinations.
