An oil-drilling company knows that it costs $65,000 to sink a test well. If oil is hit, the income for the drilling company will be $550,000. If only natural gas is hit, the income will be $428,373. If nothing is hit, there will be no income. If the probability of hitting oil is 1/65 and if the probability of hitting gas is 1/35, what is the expectation for the drilling company? Should the company sink the test well?

Ответ:
The expectation for the drilling company is $20700.76.
No, the company should not sink the test well as the cost for sinking is $65000 and our expectation is just $20700.76.
Step-by-step explanation:
Since we have given that
Probability of hitting oil =
Probability of hitting oil =
Income for the drilling company = $550,000
Income for the natural gas = $428,373
According to question, we get that
Expected for the drilling company would be :
No, the company should not sink the test well as the cost for sinking is $65000 and our expectation is just $20700.76.
