To travel from London to Brussels you take the train to Dover, the ferry to Ostend and then the train to Brussels. The train to Dover runs with probability 3/4, the ferry with probability 4/5, and the train to Brussels with probability 2/3. The three events are pairwise independent and at least one of the three transport modes (i.e., the ferry and the two trains) is operational. What is the probability that you arrive in Brussels?
