How many permutations exist in a four letter word?
4! 4 * 3 * 2 * 1 = 24
What number of permutation of the letters in the word smart?
For the first letter, you can have any of 5 choices. Then for the next, you can have any of four. Then for the next, three and so on. Thus the number of permutations can be calculated by 5x4x3x2x1. Doing this gives 120. Therefore the number of permutations of the letters in the word smart is 120.
How many ways are there to arrange the letters in ALABAMA and put four A together?

How many letters are in the German Alphabet?
There are thirty letters in the German alphabet. The first 26 are the same as the English alphabet, however they may be pronounced different. There are four extra letters, one of which is called the Esstsett.
Find the distinguishable permutations of the word Texas?
Why, sixty! (Did you know that they have taxes, in Texas?!) The calculation is 5! = 5 X 4 X 3 X 2 X 1 = 60. There are five choices of which letter to use in the first position, four choices for the next position, and so on.
How many permutations are possible of the word yard?
Imagine you have four empty buckets in which to put any of the four letters Y, A, R, D into. At first you have four letters that can be placed in any of the four empty buckets. Once you've placed a letter in a bucket you only have three letters and three empty buckets to choose from. And so on... So there are 4x3x2x1 = 24 permutations of the word YARD.
How many permutations exist in a four letter word?

How many different 4 letter permutations are there for the letters in the word toolroom?
120 four letter permutations if you don't allow more than one 'o' in the four letterarrangement.209 four letter permutations if you allow two, three and all four 'o'.1.- Let set A = {t,l,r,m,}, and set B = {o,o,o,o}.2.- From set A, the number of 4 letter permutations is 4P4 = 24.3.- 3 letters from set A give 4P3 = 24, and one 'o' can take 4 different positions in theword. That gives us 24x4 = 96 four letter permutations.4.- In total, 24 + 96 = 120 different four letter permutations.5.- If the other three 'o' are allowed to play, then you have 2 letters from set A thatgive 4P2 = 12 permutations and two 'o' can take 4C2 = 6 position's, giving 12x6 = 72four letter permutations.6.- One letter from set A we have 4P1 = 4, each one can take 4 different positions, therest of the spaces taken by three 'o' gives 4x4 = 16 different permutations.7.- The four 'o' make only one permutation.8.- So now we get 72 + 16 + 1 = 89 more arrangements adding to a total of 89 + 120 = 209 different 4 letter arrangements made from the letters of the word toolroom.[ nCr = n!/((n-r)!∙r!); nPr = n!/(n-r)! ]

How many ways can the letters in the word mississippi be rearranged if the two Ps must stay together?
Rethink the question as "How many ways can the letters of MISSISSIPI (one P) be arranged?" The (initial) answer is that this is the number of permutations of 10 things taken 10 at a time, because every time you choose a P, you simply write down two P's. That is 10 factorial, which is 3,628,800. However, since there are still multiple letters (four S's, and four I's), you need to divide by 24 twice in order to see how many distinct permutations there are. That is 3,628,800 / 16 / 16, or 14,175.
How many ways can you arrange the letters oversimplification?

What are the number of permutations of the letters of the word MATH?
For the first letter, you can choose any of the four. For the second letter, you can choose any of the remaining three. For the third letter, you can choose either of the remaining two. For the fourth letter, you don't get a choice, you have to use the one that's left. So 4x3x2x1 = 24 possible permutations.
