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. If the test predicts that there is no oil, what is the probability after the test that the land has oil?

It should be 25 %
Because (100%-45% there could be oil)= 55%(there won't be oil)
(100%-80% there could be oil)= 20 % there won't be oil
55% + 20% =75 % there wont be oil
100%-75%=25% (there will be oil)
I don't know if that's right but I tried my best @tyty6251
