Current Economic conditions: GOOD FAIR BAD
Jobs Are HARD To Get 25 145 70
Jobs Are EASY To Get 100 145 15

a. If a Household is chosen at random, what is the probability that it feels economic conditions are GOOD?

b. If a Household is chosen at random, what is the probability that it feels Jobs are EASY to get?

c. If a Household is chosen at random, what is the probability that it feels Jobs are HARD to get and economic conditions are BAD?

d. Given that a household feels Jobs are HARD to get, what is the probability that it feels current economic conditions are FAIR?

e. Given that a household feels economic conditions are GOOD, what is the probability that it feels Jobs are HARD to get?

f. What is the probability a randomly chosen Household feels Jobs are HARD to get or economic conditions are BAD?

Solution Preview

a. If a Household is chosen at random, what is the probability that it feels economic conditions are GOOD?

P (feels economic conditions are GOOD) = 125/500 =0.25

b. If a Household is chosen at random, what is the probability that it feels Jobs are EASY to get?

P (feels Jobs are EASY to ...
