4!
Four factorial.
4 * 3 * 2
= 24 permutations
------------------------
Only one.
The word "numbers" consists of 7 distinct letters. The number of permutations of these letters is calculated using the factorial of the number of letters, which is 7!. Therefore, the total number of permutations is 7! = 5,040.
10 x 9 x 8 = 720 different "permutations"
There are 720 possible permutations.
Since there are no duplicate letters in the word RAINBOW, the number of permutations of those letters is simply the number of permutations of 7 things taken 7 at a time, i.e. 7 factorial, which is 5040.
There are 24.
39916800 permutations are possible for the word INFORMATION.
Only one.
There are 6! = 720 permutations.
120 if A is treated the same as a. 360 if A is considered different to a.
120.
120?
The word "numbers" consists of 7 distinct letters. The number of permutations of these letters is calculated using the factorial of the number of letters, which is 7!. Therefore, the total number of permutations is 7! = 5,040.
It is possible to create infinitely many numbers, of infinitely many different lengths, using the digits of the given number. Using each of the digits, and only once, there are 5! = 120 different permutations.
10 x 9 x 8 = 720 different "permutations"
Only 2: CD and DC.
There are 720 of them.
