D (Round to four decimal places as needed.) An oil company executive and an executive of a mining company met during a conference. "They say 30% of the world's undiscovered oil is in the Arctic," started the oil man. "We've dri||ed 64 exploratory wells and all but 10 of them were dry. Only 3 of those 10 are economical with the oil prices being projected for the next 10 years. The good news is that 85% of these projects get environmental approvals." The mining executive replied, "It'sjust as bad in mining. We know where there's uranium, but with the current unpopularity of nuclear power, we estimate the chance of it being protable is less than 9%."
