To calculate the number of 4-digit combinations using the numbers 1-4, we need to use the fundamental counting principle. Since there are 4 options for each digit in the combination, we multiply the number of options for each digit together: 4 options for the 1st digit * 4 options for the 2nd digit * 4 options for the 3rd digit * 4 options for the 4th digit = 4^4 = 256 possible combinations.
You would get 4!/2! = 12 combinations.
There are 5,040 combinations.
I can't
how many combinations of 4 numbers are there in 7 numbers
First digit can be one of four, second can be one of the remaining three etc so 4 x 3 x 2 x 1 = 24 combinations. This is known as factorial 4 (or 4 factorial) and is symbolised as "4!".
There are 840 4-digit combinations without repeating any digit in the combinations.
There are 210 4 digit combinations and 5040 different 4 digit codes.
You would get 4!/2! = 12 combinations.
216
There are 5,040 combinations.
120 combinations using each digit once per combination. There are 625 combinations if you can repeat the digits.
There would be 9*9*9*9 or 6561 combinations.
1296 or (6^4)
4+4+4+4+4= 20
This question needs clarificatioh. There are 4 one digit number combinations, 16 two digit combinations, ... 4 raised to the n power for n digit combinations.
