Prove the following equivalences without using truth tables, and
specify at each step of your proof the equivalence law you are
using.
(a) ¬ (p ∨ (¬ p ∧ q)) ≡ ¬ p ∧ ¬ q
(b) ( x → y) ∧ ( x → z) ≡ x → ( y ∧ z)
(c) (q → (p → r)) ≡ (p → (q → r))
(d) ( Q → P) ∧ ( ¬Q → P) ≡ P
Propositional Logic
Using operator properties and other logical equivalences (not
truth tables), prove these statements.
1. ((p→r)∧(q→r)∧(p∨q))→r (tautology)
2. ¬(q→p)∧(p∧q∧s→r)∧p (contradiction)
3. (p→q)∧(p→r)≡p→(q∧r)
Using only membership tables (i.e., without Venn diagrams or set
identities), prove or disprove that (? − ?) ∪ (? − ?) and ((? − ?̅)
− ?) ∪ (? ∩ ?̅) ∪ (? − (? ∪ ?)) are equivalent. Ensure that you
fill the table completely, even if you are disproving this
equivalence, and do not skip any columns.

operators (AND,OR or NOT)

industry. (pick any) Perform a “Valuation by Comparables” analysis
by looking at the price/earnings, price/book value, price/sales,
and price/operating cash flow ratios of the firms relative to each
other and to the industry average. Which of the firms seem to be
overvalued? Which seem to be undervalued? Can you think of reasons
