think I suppost to know.
from 1000 to 9999, ie 9999 - 999 = 9000
952 of them.
An infinite amount
Oh, what a lovely question! To find the number of integers between 1000 and 9999 with all even digits, we can think of each digit place (ones, tens, hundreds, thousands) independently. In each place, we have 5 even digits to choose from (0, 2, 4, 6, 8). So, we have 5 choices for each of the 4 places, giving us a total of 5 x 5 x 5 x 5 = 625 integers with all even digits. Happy counting!
