An oil wildcatter is trying to determine whether to drill a well. If he drills, he has a 25% chance of finding oil and exploiting $10M worth of oil. If he does not find oil, he will lose $1.5M in setup costs. If he decides not to drill, he could get $1M (the lease value due to oil potential). Based on the information provided, develop a decision tree and give a recommendation for the wildcatter (the largest expected monetary value).
