What is the permutation of 5?
Permutations are the different arrangements of any number of objects. When we arrange some objects in different orders, we obtain different permutations.Therefore, you can't say "What is the permutation of 5?". To calculate permutations, one has to get the following details:The total number of objects (n) (necessary)The number of objects taken at a time (r) (necessary)Any special conditions mentioned in the question (optional).
The number of permutations of 5 things taken 2 at a time is 20?
Not quite. Number of combinations is 20, number of permutations is 10. Any 2 from 5 is 10 but in any order doubles this.
How many ways can you arrange 7CDs on a shelf?
The number of permutations of 7 things taken 7 at a time is 7 factorial, or 5040.
What is the number of ways to arrange 3 objects from a set of 8 different objects?
How many different ways can we arrange 9 objects taken 3 at a time?
How many combinations can be made from 32 items taken 4 at a time and how do you do it?
Do a web search for "permutations and combinations" to find the how. I make it 35,960.

What is the number of permutations of eight different objects taken all together?
8 different objects can be lined up in (8 x 7 x 6 x 5 x 4 x 3 x 2) = 40,320 different ways.
How many permutations are in the word math?
Since the word MATH does not have any duplicated letters, the number of permutations of those letters is simply the number of permutations of 4 things taken 4 at a time, or 4 factorial, or 24.
How many permutations are possible of the word rainbow?
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.
The number of permutations of 5 things taken 2 at a time is 20?
Not quite. Number of combinations is 20, number of permutations is 10. Any 2 from 5 is 10 but in any order doubles this.
How many arrangements of the letters in the word SCHOOLS are there?
The number of permutations of the letters in the word SCHOOLS is the number of permutations of 7 things taken 7 at a time, which is 5040. However, since two of the letters, S and O, are duplicated, the number of distinct permutations is one fourth of that, or 1260.
How many permutations are in the word mathematics?
The word MATHEMATICS has 11 letters. The number of permutations of 11 things taken 11 at a time is 11 factorial (11!), or 39,916,800.
The number of permutations of n distinct objects taken r at a time is nPr equals n divided by n-r?
nPr is n!/(n-r)!. The ! is factorial; for example 5! = 5*4*3*2*1.
How many permutations and combinations are there of 4 objects taken 3 at a time?
Permutations = 4 x 3 x 2 = 24Combinations = (4 x 3 x 2) / (3 x 2 x 1) = 24/6 = 6
How do you write a combination and permutation formula?
The combination formula is usually written as nCr representing the number of combinations of r objects at a time taken from n. nCr = n!/[r!*(n-r)!] The permutation formula is usually written as nPr representing the number of permutations of r objects at a time taken from n. nPr = n!/r! Where n! [n factorial] is 1*2*3*....*(n-1)*n
How many ways can you arrange 7CDs on a shelf?
The number of permutations of 7 things taken 7 at a time is 7 factorial, or 5040.
How many different ways can five books be arranged on a shelf?
The number of permutations of five things taken five at a time is five factorial, or 120.
