Word "CORPORATION" has got 11 letters so we could arrange 11 letters in 11P11 ways=11! ways But, Letter 'O' and 'R' are repeating thrice and twice respectively. And, presence of duplicates reduces the chances of possible arrangements. Hence it will become, 11!/(2!*3!) [Since 'R' and 'O' are repeating twice and thrice respectively]
