If you don't mind beginning the 4-digit number with one or more zeros, then
there are 10 choices for each digit, and the total number of possibilities is:
(10 x 10 x 10 x 10) = 10,000 .
If the 4-digit number can't begin with a zero, then there are only 9 choices for
the first digit, but 10 choices for each of the others, and the total number of
possibilities is:
(9 x 10 x 10 x 10) = 9,000 .

How many 6 digit numbers can be formed using the digits 0 1 2 3 4 5 6 7 8 9 if repetitions of digits are allowed?
There are 10 numbers in all including 0. The first space can be filled in 9 ways (as we have to exclude 0). The second through sixth spaces can be filled in 10 ways as 0 can be included. Totally, 9 x 10 x 10 x 10 x 10 x 10 or 9 x 10^5 digits can be formed if repetition is allowed.
How many 3 digit numbers can be formed using the digits 2 3 5 6 7 9 if repetition of digits is not allowed?
120 There are 6 digits in total. The numbers with 3 digits, with all digits distinct from each other, are the permutations of the 6 digits taken 3 at a time, and therefore there are 6*5*4 = 120 of them.
