All a household prosperous if its income exceeds $100,000. Call the household educated if the householder completed college. Select an American household at random, and let A be the event that the selected household is prosperous and B the event that it is educated. According to a survey, P(A) = 0.137, P(B) = 0.272, and the probability that a household is both prosperous and educated is P(A and B) = 0.082. What is the conditional probability that a household is prosperous, given that it is educated? (Round your answer to four decimal places.)

A= the event that the selected household is prosperous

B= the event that the selected household is educated

And that represent the final answer for this case.

Step-by-step explanation:

For this case we define the following events:

A= the event that the selected household is prosperous

B= the event that the selected household is educated

We have the following probabilities given:

For this case we want to calculate the conditional probability that a household is prosperous, given that it is educated.

So this probability can be expressed as

Using the Bayes rule we know that:

And for this case we have everything in order to replace, and we got:

And that represent the final answer for this case.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
