WitrynaThe contrapositive of a true A proposition must be true also. T If you perform the operation of contraposition on an A statement or an O statement, then the resulting contrapositive must have the same true value as the original statement. WitrynaQuestion: Write down the contrapositive form of the statement If n is a prime number and =3 then n+1 is not a perfect suar Determine the logical value of this statement. P=n is a prime number Q=n is a perfect square. a. If n+1 is not a perfect square then n is a prime or n =3. b. The statement is True. c. →Q∨P d. ¬Q∧P e.
WitrynaA proofby contrapositive, or proof by contraposition, is based on the fact that p⇒qmeans exactly the same as (not q)⇒(not p). This is easier to see with an example: Example 1 If it has rained, the ground is wet. This is a claim p⇒q, where p=“it has rained” and q=“the ground is wet”. The claim (not q)⇒(not p) will then be as follows: Witryna28 lis 2024 · If the “if-then” statement is true, then the contrapositive is also true.

The converse of tanx = 0 ⇒ x = 0 is. x = 0 ⇒ tan x = 0. ∴ Statement (b) is false. ∼ (P ⇒ q) is equivalent to p ∧∼q. ∴ Statement given in option (c) is false. No, p ∨ q and p ∧ q does not have the same truth value. Concept: Converse, Inverse and Contrapositive of the Conditional Staternent. farr and pursey
