'to use the wireless network at the airport you must pay a daily fee unless you are an employee of the airport'. define three relevant propositions w, d and e, and write the sentence using propositional logic?

The propositional logic is a statement logic in which a statement (preposition) can be either true or false.
The relevant propositions in this case are:
w- you can use the wireless network
d - you pay the daily fee
e - you are an employee
It is a disjunction, because only one of the statements must be true in order the given statement to be true.
So, we can write:
w V d -> W
V denotes OR
