One household is to be selected at random from a town. The probability that the household has a cat is 0.20.2 . The proba

Answer:

There is a 50% probability that the household has a dog, given that the household has a cat.

Step-by-step explanation:

We solve this problem building the Venn's diagram of these probabilities.

I am going to say that:

A is the probability that a household has a cat.

B is the probability that a household has a dog.

We have that:

$A = a + (A \cap B)$

In which a is the probability that a household has a cat but not a dog and $A \cap B$ is the probability that a household has both a cat and a dog.

By the same logic, we have that:

$B = b + (A \cap B)$

The probability that the household has a cat or a dog is 0.5

$a + b + (A \cap B) = 0.5$

The probability that the household has a dog is 0.4

$B = 0.4$

$B = b + (A \cap B)$

$b = 0.4 - (A \cap B)$

The probability that the household has a cat is 0.2.

$A = 0.2$

$A = a + (A \cap B)$

$a = 0.2 - (A \cap B)$

So

$a + b + (A \cap B) = 0.5$

$0.2 - (A \cap B) + 0.4 - (A \cap B) + (A \cap B) = 0.5$

$A \cap B = 0.1$

What is the probability that the household has a dog, given that the household has a cat?

20% of the households have a cat, and 10% have both a cat and a dog. So

$P = \frac{A \cap B}{A} = {0.1}{0.2} = 0.5$

There is a 50% probability that the household has a dog, given that the household has a cat.

Tim mows neighborhood lawns for extra money. Suppose that he would be willing to mow one lawn for $12, a second lawn for $15

allsm [11]

$29 will be their consumer surplus.

Consumer surplus is the difference between how much a consumer is willing to pay and how much a consumer actually does pay.

$12.00 + $15.00 + $23.00 = $50.00 (How much the consumer actually pays)

$23.00 + $26.00 + $30.00 = $79.00 (How much the consumer is willing to pay)

$79.00 - $50.00 = $29.00 (Consumer surplus)
