There are 256 of them.
You can get a list of them like this:
-- Take a very long piece of paper.
-- Write down all the numbers from zero to 9,999 . . . that's ten thousand numbers.
-- Cross out all the numbers on the list that have a 3, 4, 5, 6, 7, or 8 in them.
-- The 256 numbers you have left are the answer to your question.
There are a huge number of combinations of 5 numbers when using the numbers 0 through 10. There are 10 to the 5th power combinations of these numbers.
If the numbers can be repeated and the numbers are 0-9 then there are 1000 different combinations.

Assuming that repeated numbers are allowed, the number of possible combinations is given by 40 * 40 * 40 = 64000.If repeated numbers are not allowed, the number of possible combinations is given by 40 * 39 * 38 = 59280.
9999
The number of combinations of 7 numbers from 10 is 10C7 = 10*9*8/(3*2*1) = 120
There are 10,000 four number combinations in the numbers 0 through 9. * * * * * No, that is simply not true. The combination 1234 is the same as the combination 2134 and 2314 and 1423 etc. So, there are just 8*7*6*5/(4*3*2*1) = 70 combinations.
