Today, schizophrenia accounts for the fifth highest number of years of work lost due to disability among Americans ages 15 - 44. Roughly 30% of people with this illness are currently employed. Suppose you select a person from the U.S. population at random. State whether each question can be answered using the information given. If the question can not be answered, type "x", a. What is the probability that the person is schizophrenic? The probability - (round the answer to two decimal places) b. What is the probability that the person is unemployed? The probability - (round the answer to two decimal places) c. What is the probability that the person is unemployed and schizophrenic? The probability - (round the answer to two decimal places) d. What is the probability that the person is unemployed or schizophrenic? The probability - (round the answer to two decimal places) e. What h the probability that the person is unemployed given that he or she is schizophrenic? The probability - (round the answer to two decimal places) f. What is the probability that the person is schizophrenic given that he or she is unemployed? The probability - (round the answer to two decimal places)

Explanation / Answer

The statement does not mention the percentage of US citizens who are unemployed.
b) This question cannot be answered, therefore type in "x"

d) P(Unemployed or schizophrenic) = P(Unemployed) + P(Schizophrenic) - P(Unemployed and schizophrenic)
As this question requires probability of unemployment, it cannot be answerd, therefore type in "x"

f) P(schizophrenic | unemployed) = P(schizophrenic and unemployed)/P(unemployed)
As this question requires probability of unemployment, it cannot be answerd, therefore type in "x"
