QUESTION 2 a. Let p and q be the statements. i Construct the truth table for (-p V q) ^ q and (-p) v q. What do you notice about the truth tables? Based on this result, a creative student concludes that you can always interchange V and A without changing the truth table. Is the student, right? ii. Construct the truth tables for (-p VG) A p and (-p) v p. What do you think of the rule formulated...
please solve the following 3 questions showing the steps clearly, thumbs up will be given, note: subject Set theory and Logic Use a truth table to determine whether the following is a tautology, a contradiction, or neither. ~P∧(P⟹Q)⟹ ~Q Suppose the statement Q⟹(P∧Q⟹R) is false. Without using a truth table, determine the truth values of P, Q, and R. Give your reasons. Write the negation of the following statement. “Emirates airlines is expensive is necessary it is good and...
Prove the following is a tautology (without using a truth table) [(p →q) (q + r)] → (p → r)
NEED ASAP PLEASE WILL GIVE GOOD RATE RIGHT AWAY FOR ALL ANSWERS! A) write a regular expression (use regular expression syntax) to represent a floating point number, where the number begiywith an optional sign followed by at least 1 digit , followed by a decimal point and one or more other digits. Ex: -33.9 , +1.11919, 1.0 B) draw a dfsa to represent the regular expression
Exercise 23. I have the answer and it makes sense to me but I
don't understand what the contradiction is here.
,so Pis false. Thus values for P and Q that makes B false. Therefore B is not a R). We have seen in Example 2.24 Then tautology Exercise 21. Let A be the sentence [(P Q) n(Q → R)] (P that A is a tautology. Let B be the converse of A. Write out what B is in terms...
