In a study of flu remedy, 35% of patients had

fever relief. 49% had other symptom (congestion, etc.) relief, and 27% of patients

had relief from both.

What percent had neither fever relief nor

other symptom relief?

Given that a person had fever relief, what is

the probability that the person did not have

"other symptom" relief?

Are the events independent? Explain

carefully, citing at least two probabilities.

If a classmate noted that P(Fever

Relief|Other Symptom Relief) does not equal

P(Other Symptom Relief|Fever Relief)

thus concludes the events are not independenthow would you respond?
