another question !! ( sorry !! :P)
(just iv and v)
7 Nine cards, each of a different colour, are to be arranged in a line.
(i) How many different arrangements of the 9 cards are possible?
The 9 cards include a pink card and a green card.
(ii) How many different arrangements do not have the pink card next to the green card?
Consider all possible choices of 3 cards from the 9 cards with the 3 cards being arranged in a line.

    6 cards  can be arranged in 6!
    6! - (5!×2!) = 480
    probability : 480/6! = 2/3
