Answer:
See the attachment.
Step-by-step explanation:
A tree diagram displays all possible outcomes of two or more events, with each branch representing a possible outcome.
To draw a tree diagram representing two basketball games, start with the first game and draw two branches representing the two possible outcomes win (W) and lose (L).
From each outcome, extend two branches representing the two possible outcomes of the second game (win (W) and lose (L).
Label the end of each branch with the combined outcome of the two games, such as WW for winning both games or WL for winning the first game and losing the second game.
