Question 873514: This is a two part question. I can only figure out a)
a) How many arrangements using all of the letters of the word "parallel" are possible
8!/(3!2!)=3360
b) How many of these arrangements have all of the "l's" together?
Thank you

Think of all the l's together as one unit. So instead of 8 characters, there are now 6 with "lll" as one of the 6.
