How many unique ways can you arrange the letters in the word prior?
The word PRIOR has 5 letters and the letter R repeats twice. So the formula to calculate the answer is: 5!/2! = 5*4*3*2*1 / 2*1 = 120/2 = 60.
How many unique ways can you arrange a 5 letter word?
This is simply 5! =120 different ways.
How many ways a letter can be arranged?
=n×(n−1)×(n−2)×…… ×3×2×1. Therefore, we can arrange the letters in the word ‘FACTOR’ in 720 ways. Thus, this is the required answer.
How many unique ways are there to arrange the letters in the word four?
The answer is 4! = 24. The first space can be filled by any one of the four letters.
How many unique ways are there to arrange the word cannon?

How many arrangements of 5 letters are there?
The number of combinations possible with 5 letters is 65,780.
What is nPr formula?
Permutation: nPr represents the probability of selecting an ordered set of ‘r’ objects from a group of ‘n’ number of objects. The order of objects matters in case of permutation. The formula to find nPr is given by: nPr = n!/(n-r)!
How many ways can you arrange a 7 letter word?
5040 ways
According to the probability, 7 letter word can be arranged in 5040 ways, which is 7!.
How many ways can 3 letters be arranged?
6 ways
Therefore, the number of ways in which the 3 letters can be arranged, taken all a time, is 3! = 3*2*1 = 6 ways.

How many ways are there to arrange 4 things?
24 different ways
(Another example: 4 things can be placed in 4! = 4 × 3 × 2 × 1 = 24 different ways, try it for yourself!)
How many of the integers from 1 to 101 inclusive are divisible by either 5 or 3?
There are 20 numbers divisible by 5 between 1 and 100, and 33 numbers divisible by 3 between 1 and 100. So there are 20 + 33 = 53, so 53 numbers divisible by one or the other, but this also includes every number which is divisible by both 5 and 3 twice.
How many 5 character combinations are there?
Case(1) If the repetition of letters are allowed than different combinations can be formed by 5 letters. then the possible combination is 26 x 25 x 24 x 23 x 22 so the answer is 7,893,600.

What is nCr used for?
NCR formula is used to find the possible arrangements where selection is done without order consideration. NCR formula is used to find the number of ways where r objects chosen from n objects and the order is not important. It is represented in the following way. nCr=nPrr!
What is nCr in math?
In mathematics, combination or nCr, is the method of selection of ‘r’ objects from a set of ‘n’ objects where the order of selection does not matter. nCr = n!/[r!( n-r)!]
