a. In what order are the operations in the following propositions performed? i. P ∨   ¬q ∨   r ∧   ¬p ii. P ∧   ¬q ∧   r ∧   ¬p iii. p ↔ q ∧   r → s b. Suppose that x is a proposition generated by p, q, and r that is equivalent to p ∨   ¬q. Write out x as a function of p, q, and r, and then give the truth table for x
