BP has three potential sites where it can build a drilling rig. Due to its past experience, the CEO has instructed his management team to chooseno more than onesite.

The costs, the revenues and the estimated outcomes for each site are given in the table below.

Probabilities for the different outcomes
E3 (Dry) Expected revenue:$0M	E2 (Wet) Expected revenue: $5M	E1 (Overflowing) Expected revenue: $30M	Costs (in million $)	Site
0.2	0.8	0	2	A
0.2	0.5	0.3	8	B
0.4	0.4	0.2	6	C

For example, it costs $8M to build a drilling rig in site B. Theres a 30% chance for E1 with potential revenue of $30M; 50% chance for E2 with potential revenue of $5M; and a 20% chance for E3 with zero revenue.
