hello,

I'm not a math student,but I happened to need probability science to solve something :
I have 14870 words , and I want to build 10-word-sentence using them ,how many sentence can be formed using this number of words,keeping in mind that a word can not be repeated in the same sentence
and how you did it ?

thanks in advance,

For the first word you have 14870 words to choose from. Once you select one, then for the second word there are 14869 remaining to choose from. So the total number of 2-word combinations is 14870 x 14869. (Note that this assumes that the order of words in the sentence mat vary - so the combination "cat tree" is considered to be different than "tree cat.") Then for the third word there are 14868 left to choose from, so the number of possible 3-word sentences is 14870 x 14869 x 14868. Continue using this approach to work out the number of 10-word sentences.

Thanks this is helpful
