In p-->q what's the premise ?

(b) What is the truth value of ~ (p V q) - r?

1. Given that p and q are True and r and s are False, find the truth value of the statement. (~r) = (pA(r → (~qV~s))) 2. (а) Rewrite the statements in the form of " i. x, No irrational numbers are integers. The number -4 is not equal to the square of any real number. ii. (b) Rewrite the statements in the form of "3 i. ii. x, Some exercises have answers. Some real numbers are rational. (c) Determine the truth value of the statements where D = E = {-9, –3,0,3,9}. Hence, write the negation of the statements. i. i. x in D, 3y in E such that x +y = 0. 3x in D such that Vy in E, x + y = y. 3. Find the union, intersection, and difference (A - B) of the following pairs of sets. (a) A = The set of positive odd integers less than 15. B = The set of positive even integers less than 16. (b) A = (f,l,o,w,e,r} B = {c,l, o,n, e}

Which option below (a,b,c, or d) represents the small world that this inference being made is NOT valid.Inference= (∀x)(Fx->Gx) and Fa; therefore, (∀x)Gx.a) Individuals: a, b; Predicates: Gbb) Individuals: a, b; Predicates: Fa, Fb, Ga, Gbc) Individuals: a, b; Predicates: Fa, Ga, Fbd) Individuals: a, b; Predicates: Fa, Ga

7. Use all of the premises to determine a alid conclusion for the following argument. ~m Vt t → -d e Vg e → d ..?
