Based on geological studies done on land in east texas, a petroleum company believes the probability of finding high-quality oil is 35%, medium-quality oil is 49%, and no oil is 16%. since drilling can be expensive, the petroleum company also plans on doing a soil test (since certain soil types are more apt to detect the presence and quality of oil). for example, the petroleum company knows that in 23% of high-quality oil finds, 17% of medium-quality oil finds, and 15% of no oil finds, the soil is type a. so, for east texas land… find the probability the soil was not type a or no oil is found.
