There are 9C3 = 84 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.
In other words, how many 4 digit combination locks are there using the digits 0-9 on each wheel. There are 10×10×10×10 = 10⁴ = 10,000 such combinations.
There are 210 4 digit combinations and 5040 different 4 digit codes.
Exactly 3,628,800, or 10!.
10!/3! = 604800 different combinations.

Oh, what a happy little question! There are 100,000 different 6-digit combinations that can be made from 0 to 99. It's like painting a beautiful landscape with numbers - each combination is unique and special in its own way. Just imagine all the possibilities and let your creativity flow!
If there are no restrictions on duplicated numbers or other patterns of numbers then there are 10 ways of selecting the first digit and also 10 ways of selecting the second digit. The number of combinations is therefore 10 x 10 = 100.
There are 9C3 = 84 combinations.
There are 4,500 combinations.
1,000. The list looks just like the counting numbers from 000 to 999 .
There are 5*4*3*2 = 120 such numbers.
That's exactly all the numbers you need to count from 000,000,000 to 999,999,999.There are one billion of them.
