The premises will always occur to the le, separated by commas; the symbol ∴ is used to separate the premises from the conclusion and can be read as “therefore” (or “thus”, or “hence”)

(p ∨ q) (p → q) (p → r) ∴ (p → (q ∧ r)) if p then q; and if p then r; therefore if p is true then q and r are true q) ∧ ¬(p e negation of (p and q) is equiv to (not p or not q)

β: Coefficient in regression statistics, often subscripted to indicate different coefficients: y = α + β1x1 + β2x2 + ε; also type II error; related, 1 – β is called the “power” of a statistical test Γ: A particular statistical distribution; also used to denote a game

All statements in an argument, except for the final one are premises (or assumptions or hypotheses) The final statement is the conclusion An argument is valid when all premises are true, the conclusion is also true In fact, the conclusion is ‘inferred’ or ‘deduced’ from the truth of the premises

Premise 1: p → q Premise 2: ∼ q Conclusion: ∴ ∼ p Now that we know this form is valid, we can use it to demonstrate the validity of an argument without having to go through the truth table method again (we already did it once, which is enough) The name for this valid argument form is: The Law of Contraposition

∃ (the existential quantifier) means “there exists” and was first used in the 1897 book For-mulaire de mathematiqus by Giuseppe Peano (1858-1932) (the Halmos tombstone) means “QED”, which is an abbreviation for the Latin phrase quod erat demonstrandum (“which was to be proven”)
