Jason inherited a piece of land from his great-uncle. owners in the area claim that there is a 45% chance that the land has oil. jason decides to test the land for oil. he buys a kit that claims to have an 80% accuracy rate of indicating oil in the soil. what is the probability that the land has oil and the test predicts it?

0.09 or 9%.            

Step-by-step explanation:  

We have been given that Jason inherited a piece of land from his great-uncle. Owners in the area claim that there is a 45% chance that the land has oil.

We will use conditional probability formula to get our answer.

We have been given that probability that land has oil is 45% or 0.45.

Let us find the probability that test predicts an inaccurate result. As probability of predicting an accurate test is 80%, so probability that test will be inaccurate will be 100%-80%=20% or 0.20.  

Therefore, the probability that the land has oil and the test predicts it will be 0.09 or 9%.
