Probability
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 1/2. Which of the following gives the probability that a person can travel from station P to station Q? Select one: O a. 7/8 O b. 1/8 O c. 5/8 O d. 3/4 O e. None of the other choices
