A passenger just gets of a flight from San Francisco to Denver. What is the probability
(a) What is the probability that they flew on (i) on a plane that re-circulated the air? (ii) will have post-flight respiratory problems?
(b) he/she will have flown on a plane with re-circulated air or will experience post-flight respiratory prob- lems?
(c) If he/she experienced post-flight respiratory problems, what is the probability they flew on a plane where the air was not re-circulated?
(d) Are the events ‘RA’ and experiencing ‘post-flight respiratory problems mutually exclusive events? Independent events?
