If you allow zero to be in the first positions (0000 and 0001, etc) then there are 10,000 combinations (0000 to 9999). If zero can not be in te first position, remove 0000 to 0999 (1,000 combinations), so there are 9,000 combinations (1000 to 9999).
If your looking for 4 digit lottery answers here they are.
Of the 10,000 4-digit numbers 5040 are non-repeating, 4320 one-repeating (doubles), 270 two-repeating (dual-doubles), 360 one-tripled, and 10 quadruples. Since a non-repeating number has 23 more siblings, we can divide 5040 by 24 to obtain 210 distinct non-repeating-digit numbers which are listed below.

How many 4 digit combinations can be made from 6 digits?
If the 6 digits can be repeated, there are 1296 different combinations. If you cannot repeat digits in the combination there are 360 different combinations. * * * * * No. That is the number of PERMUTATIONS, not COMBINATIONS. If you have 6 different digits, you can make only 15 4-digit combinations from them.
How many 5 digit combinations are there in six digits?
about 1,0000000000000
How many 2 digit combinations can be made with 2 digits?
Only one.
How many 2 digit combinations can be made from 0 to 9 digits?
45 In combinations, the order of the digits does not matter so that 12 and 21 are considered the same.
What combinations can you make with numbers 1 4 7 2 5 8 0?
Assuming the digits cannot be repeated, there are 7 combinations with 1 digit, 21 combinations with 2 digits, 35 combinations with 3 digits, 35 combinations with 4 digits, 21 combinations with 5 digits, 7 combinations with 6 digits and 1 combinations with 7 digits. That makes a total of 2^7 - 1 = 127: too many for me to list. If digits can be repeated, there are infinitely many combinations.
How many combinations are there for a four digit number?
64
How many different combinations can you make using 2 3 6 and 9?
If you use them only once each, you can make 15 combinations. 1 with all four digits, 4 with 3 digits, 6 with 2 digits, and 4 with 1 digit. There is also a combination containing no digits making 16 = 24 combinations from 4 elements.
How many different combinations can you get from 1855?
Twelve in all: One of 4 digits, Three of 3 digits, Four of 2 digits, Three of 1 digit, and One with no digits. In mathematical terms, the last IS a combination, but in common usage, probably not.
How many 9 digit combinations are there from 1 to 20-?
There are 167960 9 digits combinations between numbers 1 and 20.
How many 4 digit combinations can be made with 4 digits?
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.
How many combinations in 3879?
There are infinite combinations that can make 3879
How many combinations can you get from a 3 digit code from 1 to 3?
Allowing repetitions, there are 9 combinations. Without repeated digits, there is only one combination of 3 digits from 3.
