After buying a computer system, Sim Thomas must decide whether to purchase (1) a complete service contract at a cost of $1300, which would cover all maintenance costs; (2) a partial service contract at a cost of $700, which would require Thomas to pay the first $1000 of the maintenance and the rest will be covered by the service agreement; or (3) no service contract. The consequences, costs and probabilities are given in the following table:

MAINTENANCE REQUIRED $	0	500	1000	1500	3000
Probabilities	0.2	0.2	0.2	0.3	0.1
