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.
Please let me know if these answers are correct
