In how many ways can the letter of the word SECTION be arranged if the consonants must always be in the order in which they occur in the word itself?
without restrictions there would be 7! ways or 5040
The EIO can be arranged in 3! or 6 ways, but we want only one of these sequences.
so the number of arrangements is 5040/6 = 840
(somebody check my thinking on this)
wrong its 210
Don't know why, that's just what the back of the book says :s
