Question 201378: I have been mulling over this problem for quite some time, and I think I have it right but I just need someone to look at it and confirm for me.
Here is the statement that I am presented with:
"If Verizon Wireless must remove installed equipment from a vehicle or fixed location in order to return it, then you will be charged a service fee."
My assignment requires me to put this in symbolic form and then create a truth table for it. Here is what I got.
p: Verizon Wireless must remove installed equipment from a vehicle
q: Verizon Wireless must remove installed equipment from a fixed location
r: You will be charged a service fee
In symbolic form: (p v q) --> r
and the truth table (in a weird format because of the text box, sorry):
p: T T T T F F F F
q: T T F F T T F F
r: T F T F T F T F
(p v q): T T T T T T F F
(p v q) -> r: T F T F T F T F
Any insight you can provide is much appreciated. Thank you in advance.
