An anagram is a rearrangement of all the letters in a word. Example: page--->gape, pgea..

a) Find the number of 7 letter anagrams possible for the letters in GUITARS.

I did 7!=5040...is that correct?

b) Find the probability of randomly choosing an anagram that starts with T.

There are 720 options for each letter because 5040/7=720. So 720/5040=1/7 which is answers...is this correct?

c) Mentally picture all of your 7-letter anagrams organized alphabetically in a long list, then write the first two and the last two in the list.

First two:

AGIRSTU

AGIRSUT

Last two:
