Are you asking,
"How many five-digit numbers are there?
Sorry! I meant"how many five digit odd numbers are there"?
To find the number of five-digit numbers, we need to determine the range of values for each digit.
For the first digit, it cannot be zero, so we have nine options (1-9).
For the next four digits (second, third, fourth, and fifth), they can each be any of the ten digits (0-9).
Therefore, the total number of five-digit numbers can be calculated by multiplying the number of options for each digit:
9 options for the first digit, and 10 options for each of the next four digits.
So, the number of five-digit numbers is: 9 * 10 * 10 * 10 * 10 = 90,000.
