How many 4 number combinations using digits 1357 one and only once?
To calculate the number of 4-digit combinations using the digits 1, 3, 5, and 7 exactly once each, we can use the permutation formula. There are 4 choices for the first digit, 3 choices for the second digit, 2 choices for the third digit, and 1 choice for the fourth digit. Therefore, the total number of combinations is 4 x 3 x 2 x 1 = 24. So, there are 24 possible 4-digit combinations using the digits 1, 3, 5, and 7 exactly once each.
How many 3 digit combinations are there in the numbers 1 to 9?
It depends. If you can only use each number once, there are 720 combinations. If you can use numbers multiple times, then there are 1000 combinations, by using all numbers from 000 to 999.
How many 5 digit combinations are there for numbers 1 to 45?

How many 3 digit combinations are there in 1 to 21?
I am assuming you mean 3-number combinations rather than 3 digit combinations. Otherwise you have to treat 21 as a 2-digit number and equate it to 1-and-2. There are 21C3 combinations = 21*20*19/(3*2*1) = 7980 combinations.

6 of them.
How many answers are there for a 3 digit keypad?
There are 27 possible combinations.
How many possible combinations can a 3-digit safe code have?
A 3-digit safe code can have combinations ranging from 000 to 999. This gives a total of 1,000 possible combinations, as each digit can be any number from 0 to 9. Therefore, the total number of combinations is 10 (choices for the first digit) × 10 (choices for the second digit) × 10 (choices for the third digit), which equals 1,000.
How many combinations of 2 and 3 digit number using 4 and 8?
the answer is = first 2-digit number by using 48= 28,82 and in 3 digit is=282,228,822,822
How many 4 digit combinations can be made using numbers 1 2 3 4 6?
120 combinations using each digit once per combination. There are 625 combinations if you can repeat the digits.
How many number of combinations can be formed by using numbers123456 within 500?
To find the number of combinations of the digits 1, 2, 3, 4, 5, and 6 that form numbers less than 500, we can consider the constraints based on the first digit. If the first digit is 1, 2, or 3, all combinations of the remaining digits can be used. If the first digit is 4, only combinations that result in a two-digit number can be formed. The total combinations can be calculated based on these conditions, but generally, you can form various 1-digit, 2-digit, and 3-digit numbers, totaling around 120 distinct combinations.
How many combinations can you get from a 3 digit code from 1 to 3?
Allowing repetitions, there are 9 combinations. Without repeated digits, there is only one combination of 3 digits from 3.
What is a list of 5 digit combinations starting with a 3 and numbers can be repeated?
The number of four-digit combinations is 10,000 .Stick a '3' before each of them, and you have all the possible 5-digit combinations that start with 3.There are 10,000 of them. They run from 30,000 to 39,999 .
How many 3 digit combinations using digits 0 to 9 repeating allowed?
To find the number of 3-digit combinations using the digits 0 to 9 with repetition allowed, we consider that each digit can be any of the 10 digits (0-9). Since there are 3 positions in the combination, the total number of combinations is calculated as (10 \times 10 \times 10), which equals 1,000. Therefore, there are 1,000 possible 3-digit combinations.
