Figure 17-3. Hector and Bart are roommates. On a particular day, their apartment needs to be
cleaned. Each person has to decide whether to take part in cleaning. At the end of the day,
either the apartment will be completely clean (if one or both roommates take part in cleaning),
or it will remain dirty (if neither roommate cleans). With happiness measured on a scale of 1
(very unhappy) to 10 (very happy), the possible outcomes are as follows:
Clean
Hector's Decision
Don't clean
Hector's happiness = 6
Hector's happiness = 10
Clean
Bart's happiness = 7
Bart's happiness = 2
Bart's
Decision
Hector's happiness = 2
Hector's happiness = 5
Don't clean
Bart's happiness = 10
Bart's happiness = 4
Refer to Figure 17-3. If this game is played only once, then the most likely outcome is that
Hector and Bart both clean.
Hector cleans and Bart does not clean.
Bart cleans and Hector does not clean.
neither Hector nor Bart cleans.
