A machine shop has to decide whether to repair, refurbish, or replace a machine (or do nothing).The estimated monetary returns are given below for different possibilities of future demand (low, medium, or high).

	0.3	0.5	0.2
	Low	Medium	High
Do nothing	2	2	2
Repair	3	4	5
Refurbish	4	10	12
Replace	-2	8	20

The first row indicates the probability of the possible future demand situation.

As an example, if repair is carried out, and the future demand is high, the monetary return would be 5.
