Each of the coins in a collection is distinct and is either silver or gold. In how many
different ways could all of the coins be displayed in a row, if no 2 coins of the same color
could be adjacent?
(1) The display contains an equal number of gold and silver coins.
(2) If only the silver coins were displayed, 5,040 different arrangements of the silver coins
would be possible.
The answer is C.
I was wondering how to actually find the possible ways of arrangement. Is it 7! * 8?
