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 that there is no oil? a. 0 b. 0.09 c. 0.11 d. 0.44

Answer from: elsauceomotho

B. 0.09

Explanation:

Probability that the land has oil = 45%

= 0.45 (converted into decimal)

Probability of accuracy of the kit = 80%

= 0.80 (converted into decimal)

Probability that the kit detects no oil = Total probability - Probability of accuracy of the kit

= 1 - 0.80 [total probability of any event is always 1]

= 0.20

Probability that the land has oil and the test predicts that there is no oil = Probability that the land has oil x Probability that the kit detects no oil

= 0.45 x 0.20

= 0.09

Answer from: gunnatvinson

The correct answer is option A.

Explanation:

We have been given that

Probability that the land has oil = P_o = 45% = 0.45

Accuracy rate of the kit indicating the oil in the soil = $P_{k,o}$ = 80 %= 0.80

Rate of the kit indicating no oil in the soil = $P_{k,n}$ 1 - 0.8 = 0.2

Probability of the land has oil and test kit predicts that there is no oil:(And means multiplication, so we will multiply the above two probabilities)

$P_o\times P_{k,n}=0.45\times 0.2=0.09$

Hence, the probability that the land has oil and the test predicts that there is no oil is 0.09.
