Imagine that a family decides to play a game each night. They all agree to use a tetrahedral die (i. e., a four-sided
pyramidal die where each of four possible outcomes is equally likely-see the image at the end of this lesson) each night
to randomly determine if they will play a board game (B) or a card game (C). The tree diagram mapping the possible
overall outcomes over two consecutive nights will be developed below. If CB represents the family playing a card game Monday and a board game Tuesday, what does BC represent? List the outcomes where exactly one board game is played over two days. How many outcomes were there where exactly one board game is played over two days?
