A tram company runs two tram routes from station ?P to station ?Q. The first route is a direct tram, the green line. The second route involves changing trams at an intermediate station: passengers take the blue line from station ?P to station ?R and then the yellow line from station ?R to station ?Q. The events of the three tram lines running are mutually independent and each tram line runs with probability 1/21/2. Which of the following gives the probability that a person can travel from station ?P to station ?Q?
