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.

Answer:

0.36 = 36% probability that the land has oil and the test predicts it

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

45% chance that the land has oil.

This means that $P(A) = 0.45$

He buys a kit that claims to have an 80% accuracy rate of indicating oil in the soil.

This means that $P(B|A) = 0.8$

What is the probability that the land has oil and the test predicts it?

This is $P(A \cap B)$ . So

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

$P(B \cap A) = P(B|A)*P(A) = 0.8*0.45 = 0.36$

0.36 = 36% probability that the land has oil and the test predicts it

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.

Matt's steps will be more complicated since Annie is using a program to do the constructions hers would probably be precise and easy.

Hi... So for this homework question It says " Amy bought 2 and 1/2 gallons of paint for $60. What is the cost for 1 gallon of pa

andrey2020 [161]

I'm sorry but the solution you proposed was a bit hard to follow, so I'll just post my solution: we convert "2 and 1/2" to a single fraction:

$2+\dfrac{1}{2} = \dfrac{4}{2}+\dfrac{1}{2}=\dfrac{5}{2}$

So, we know that 5/2 gallons cost 60 dollars, which means

$\dfrac{5}{2}g=60$

To find the cost of a single gallon, we have to solve the equation for g:

$g = 60\cdot \dfrac{2}{5} = 24$
