Exhibit 5-1
In a survey of airline travelers, subjects were observed in the coach section of airplanes to determine if men or women are bothered by a seatmate of the opposite gender using the common armrest. ("Passengers who were asleep or lovers cuddled together were not counted, since these were considered confounding circumstances.")The table below contains data gathered in that study. Suppose one of these passengers was randomly selected. Use the information in the table to answer the questions below. In showing your work, define and use appropriate notation.
-In the study in Exhibit 5-1, passengers were also classified by age: Suppose one of these passengers was randomly selected. Calculate the probability that:
a)The passenger is under 40, given that she is female.
b)The passenger was bothered, given that the passenger was over 40.
c)The passenger was male and over 40.
