(b) Draw a game tree for a game in which First and Second each have three possible actions (Sit, Stand, or Jump) at each node. How many of the two node types are there?

(c) Draw a game tree for a game in which First has four possible actions (North, South, East, or West) at each node and Second has two possible actions (Stay or Go) at each node. How many of the two node types are there?
