Question

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



0.11



0.36



0.44

Answer 1

Probability of oil = 0.45

Probability kit is right = 0.80

 probability of oil = 0.80 * 0.45 = 0.36

Answer 2

HEYA!!!!!

So, Probability of oil= .45

Probability of that kit is right= .8

Probability that land has oil=
$.45 \times .8 = .36$
So C) is the correct answer

Hope it helps you......
