0-9 digits how many four digit combinations can you have?

Answer 1

9

Answer 2

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).

Answer 3

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.
