Answer:
8,996,734,079 numbers
Step-by-step explanation:
First let's find the number of ten-digit numbers.
The maximum ten-digit number is 9,999,999,999 and the minimum is 1,000,000,000. So the number of ten-digit numbers is:
Now, to find the number of ten-digit numbers with at least two equal digits, we can find the number of ten-digit numbers with all digits different, and then subtract this amount from the total ten-digit numbers.
To find the number of ten-digit numbers with all digits different, we can use the following logic:
The first digit can have 9 different values (0 not included), the second can also have 9 (one digit used), then the third can have 8 (two digits used), the fourth can have 7, and so on. So we have that:
Then the number of ten-digit numbers with at least two equal digits is:
