To be a four digit number the highest value digit (the thousabdth's position) cannot be zero because if it is then it ceases to be a four digit number. Hence the thousandth position digits can be 1 through 9 both inclusive. The other three digits can be 0 through 9 both inclusive. Therefore the number of four digit numbers you can make is
9 x 10 x 10 x 10 = 9000. To enumerate them all a simple computer program in BASIC or C can easily be written.
Assuming that 00, 01, 02, etc. count as two digit numbers, then there are one hundred (1 through 99 and including 0).If you are not allowed to count 00, 01, 02, 03, 04, 05, 06, 07, 08, or 09 because they simplify to one digit numbers, then you have ten less--so a total of ninety two digit numbers.

If you count 00, 01 though to 09 as 2 digit numbers then you have a 19% chance...There are 100 numbers and 19 contain the number 8....08, 18, 28, 38, 48, 58, 68, 78, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 98ANOTHER ANSWERTwo digit numbers start at 10 and continue to 99. Of these 90 numbers, 18 have at least one 8 in it. That gives 18/90 = 20% chance (exactly).

Yes. The zero is only acting as a place holder.
