How many permutations exist of the letters a b c d taken two at a time?
12
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.
How many different ways could Henry have arranged 20 photographs?
The number of permutations of 20 things taken 20 at a time is 20 factorial or 2,432,902,008,176,640,000.
How many permutations and combinations are there of 8 objects taken 5 at a time?
For the permutation the equation is (8!)/(5!) assuming there is no replacement. Which is 8*7*6 = 336 For combinations the equation is (8!)/((5!)(8-5)!) = (8!)/((5!)(3)!) = (8*7*6)/(6) = 56
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 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.
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.
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).
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.
How many permutations exist of the letters a b c d taken four at a time?
Since you are using in the arrengement the all 4 letters, then there are 4! = 4*3*2*1 = 24 permutations.
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.
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 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 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.
How many different batting lineups can a manager make with thirteen batters?
The number of permutations of 13 things taken 13 at a time is 13 factorial, or 6,227,020,800.
