Question

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?

The answer is said to be 5/12 but i really dont understand why or how, I've been reading through the material and dont get it, Please help

Definition Definition Measure of central tendency that is the value that occurs most frequently in a data set. A data set may have more than one mode if multiple categories repeat an equal number of times. For example, in a data set with five item—3, 5, 5, 29, 473—the mode is 5 because it occurs twice and no other value occurs more than once. On a histogram or bar chart, the element with the highest bar represents the mode. Therefore, the mode is sometimes considered the most popular option. The mode is useful for nominal or categorical data (e.g., the most common color car that users purchase), but it is problematic for continuous data because it is more likely not to have any value that is more frequent than the other.
