Question

How many different arrangements can be made using all of the letters in the word MOVIE?
144?

Answer 1

you're permuting 5 objects all distinct. 5!=120

Answer 2

If they were not distinct, for example how many different arrangements of stools, you have to use something called the partition fomula. There are two s's, two o's, one t, one l. So the arrangements are 6!/(2!2!1!1!)=180

Answer 3

i did 5!/(5!)(4!)(3!)(2!).... but i understand now
i see what i did wrong

Answer 4

You should have done 5!/(5-5)! = 5!/0! = 5!
