Please I need help with this for better understanding and clarity. Thank you. (e Three different Mathematics books,four different French books and two different Physics books are to be arranged on a shelf.How many different arrangements are possible if
i. the books in each particular subject must all stand together only the French books must be in the first position on the shelf whilst the others
ii. must also always be together but not in the first position
iii. all the three subject matters can be arranged anyhow.
