Let's start with the range 0 to 9999. The numbers without a 5 are found by picking 4 digits out of (0,1,2,3,4,6,7,8,9). So the number without a 5 is 9^4=6561 So the number with at least one 5 is 90005832=3168. How many numbers are there from 1000 to 1999 that do not have any repeated digits? Lets see in 1099. A: From 1000 to 9999 , all are 4 digited integers. of such integers = 6 7 8 5 = 1680. How many positive integers between 1000 and 9999 inclusive: a.) There is no restriction to other digits. d. How many odd integers from 1000 through 9999 have distinct digits?
