How many possible 4-digit number combinations are there?

Answer 1

0000 - 9999

So, 10,000 in total

Answer 2

4 Digit Number Combinations

Answer 3

4 Number Combinations

Answer 4

Depends. Are you allowed to have leading zeros?

If not, then there are 9 possible digits for the first number, 10 for the second, 10 for the third, and 10 for the fourth. That would give you 9*10*10*10 = 9000 different combinations.

If you allow the number to start with a zero, then the answer is 10000.

Answer 6

let's start with the assumptions

1) you have 10 digits (your working in base 10)
2) the order matters (eg. 1234 is a different number than 2134)
3) you can have the same digit appear multiple times (eg. 2234)

the appropriate equation is for ordered permutations with replacement and is this...

number of permuations = n^r
where n = number of different digits (10 in this case)
and r = number of digits "chosen" ie 4 in this case.

so that the number of combinations = 10^4 or 10,000

if you think about it, the number of combinations of 10 digits " chosen 1 time = 10 (0,1,2,3,4,5,6,7,8,9)

likewise, 0000 to 9999 is 10,000 combinations

Answer 7

9999 if 0001 is considered a 4 digit number, 10,000 if you include 0000

otherwise if you are defining a 4 digit number to start with 1000, then the answer is 9*10*10*10=9000

Answer 8

I think what you mean to ask is how many possible combinations are there? 9^4 = 6561

Answer 9

ok you will be surprised!
from 0000 to 000.9 =10
and 0001 to 001.9=10
eventually you have a number like 1.999
so many people will be so far off this one !
then you end up with a number like 10.99
from 0010 to 0011 is 100 number sequences
and then a number like 100.9
from 0100 to 0101 is 10 numbers
and then the 1000's etc
so i worked it all out and your answer is """35890""".that is if you don't include negative numbers,if you do just double and take 1 away due to the fact there is only one 0000

Answer 10

There are 10000 four digit combinations

0000 through 9999

Answer 11

To answer your question strictly, it's 10 C 4 = 210 combinations.

However, you probably meant "permutations", in which case you can refer to all the other answers.
