1. Given premises: - (1) I would read a book or go to gym on Sunday. - (2) If Peter does not go to the gym Sunday, I would not go to the gym on Sunday. - (3) If Peter would go to the gym on Sunday, he would take a rest on Saturday. - (4) Peter does not take a rest on Saturday.Prove the conclusion: I read a book on Sunday. You should first express the premises and the conclusion using propositional logical expressions. Use rules of inference and follow the format for formal proofs discussed in class.
