Use propositional logic to prove the following argument is valid. If Alice gets the office position and works hard, then she will get a bonus. If she gets a bonus, then she will go on a trip. She did not go on a trip. Therefore, either she did not get the office position or she did not work hard or she was late too many times.

a) Define your propositions [5 points]: O = W = B = T = L =

b) Write down the logical argument [8 points]:

c) Proof sequence [12 points]: Steps: Reason: 1. 2. 3. …
