In a Board Game, a Murder Occurs

Short Answer

In a board game, a murder occurs. There are six possible suspects (Plum, White, Green, Mustard, Peacock, Scarlet), six possible weapons (candlestick, knife, lead pipe, revolver, rope, wrench), and nine possible rooms where the murder can take place. At the beginning of the game, three cards are chosen at random (one suspect, one weapon, one room).
A) How many different ways can these three cards be chosen?
B) If the game maker decided to add another possible suspect, Orange, to cover all the colors in the rainbow, how many more possibilities are there?
