How many 4 digit numbers have only odd numbers?

Answer 1

To find the number of 4-digit numbers with only odd digits, we need to consider the options for each digit. Since odd digits are 1, 3, 5, 7, and 9, there are 5 choices for each digit. Therefore, the total number of 4-digit numbers with only odd digits is calculated as 5 x 5 x 5 x 5 = 625. So, there are 625 4-digit numbers that have only odd numbers.

Answer 2

Oh, dude, we're talking about 4-digit numbers with only odd digits? Alright, so each digit can be 1, 3, 5, 7, or 9, right? That's 5 options for each digit. So, to get the total number of 4-digit numbers with only odd numbers, you just multiply 5 by itself 4 times, which gives you 625. Easy peasy, lemon squeezy!

Answer 3

Well, honey, to find the number of 4-digit numbers with only odd digits, you gotta realize that each digit has 5 choices (1, 3, 5, 7, 9). So, you just multiply those choices together for each digit to get 5 x 5 x 5 x 5, which equals 625. So, there are 625 4-digit numbers that have only odd numbers. Hope that clears things up for ya, sugar!

Answer 4

625. Here's how:

There are five odd digits {1,3,5,7,9} so our numbers will be made using only these digits. This is the same number of possibilities as if you had a base 5 number system where the allowed digits are {0,1,2,3,4}. For a 1 digit base-5, there are 5 possibilities, for a two digit base-5 there are 5² = 25 possibilities, so for a 4-digit, there are 5^4 = 625possible. This is the same number you will have with only using odd digits.
