An oil company purchased an option on land in Alaska. Preliminary geologic studies assigned the following prior probabilities. P(high-quality oil) = 0.55 P(medium-quality oil) = 0.25 P(no oil) = 0.20 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. P(soil | high-quality oil) = 0.25 P(soil | medium-quality oil) = 0.80 P(soil | no oil) = 0.25 What is the new probability of finding oil (to decimals)? According to the revised probabilities, what is the quality of oil that is most likely to be found?
