An oil company purchased an option on land in Alaska. Preliminary geologic studies assigned the following prior probabilities.
P(high-quality oil) | = | 0.3 |
P(medium-quality oil) | = | 0.4 |
P(no oil) | = | 0.3 |
If required, round your answers to two decimal places.
(a) | What is the probability of finding oil? | ||||||||||||||||||||||||||||||||||||
(b) | After 200 feet of drilling on the first well, a soil test is taken. The probabilities of finding the particular type of soil identified by the test are as follows. | ||||||||||||||||||||||||||||||||||||

Given the soil found in the test, use Bayes' theorem to compute the following revised probabilities (to 4 decimals). | |||||||||||||||||||||||||||||||||||||
