EXAMPLE 2.2.3 Symbolize this statement, taken from the instructions for IRS From 1040, line 10: In 5 – 8, write the converse of the statement in symbolic form. The inverse is "If a polygon is not a quadrilateral, then it does not have four sides." q →p is the . To get the contrapositive, we must switch AND negate the propositions. we can form new conditional statements . Use the statement: Any two points are collinear. The following contrapositive statement is logically equivalent to the original if-then statement: "If I do not help you with your homework, then you will not do the dishes." Example 7: Write four related conditional statements (if-then form, the converse, the inverse, and the contrapositive) of “ Guitar players are musicians.” Decide whether each statement is true or false. The logical converse and inverse of the same conditional statement are logically equivalent to each other. of p →q ¬ p → ¬ q is the . Converse , Inverse and Contrapositive Let us start our discussion with a term called a conditional statement. Note: As in the example, the contrapositive of any true proposition is also true. Fancy. * The converse … Use the statement: Any two points are collinear. Next: Contrapositive Example with Sets. The mini-lesson targeted the fascinating concept of converse statement. of p →q. The inverse of a statement is taking the negation of each variable so with the last example we would have the original statement of: If A then B or A -> B The inverse would be If ~A then ~B or ~A -> ~B Contrapositive The contrapositive of a statement is sort of a combination of the converse and the inverse. Sticking with our example: If 1+1=2, then 2+2=3. I come to class whenever there is going to be a quiz. EXAMPLES Direct statement: If you drink Pepsi, then you are happy.

The converse of the conditional statement is “If Q then P.” The contrapositive of the conditional statement is “If not Q then not P.” The inverse of the conditional statement is “If not P then not Q.” We will see how these statements work with an example. If-Then Form … Now you can easily find the converse, inverse, and contrapositive of any conditional statement you are given! Contrapositive: If you aren't happy, then you don't drink Pepsi. Inverse. 16) If today is Monday, then it is not the weekend. Elementary Foundations: An introduction to topics in discrete mathematics Jeremy Sylvestre. Given a statement p q, the contrapositive is the statement q p, the inverse is p q and the converse is q p. A statement and the contrapositive are equivalent, then, if we have proved the statement, the contrapositive is proved too. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Try these examples out: In 1 – 4, write the inverse of the statement in symbolic form. And second: how contrapositive is equivalent to conditional statement? Let p be the statement ''I'm sick'' and qbe the statement ''I go and see a doctor''.The p qmeans ''If I'm sick, then I go and see a doctor''. The Converse, Inverse and Contrapositive. converse. So, by the law of contrapositive, the inverse and the converse also have the same truth value. Finally, we move on to the contrapositive. Example: Find the converse, inverse, and contrapositiveof “It raining is … Converse vs. Inverse In inverse statements, the opposite of the original hypothesis and conclusion is written, whereas in a converse statement, only the hypothesis and the conclusion is exchanged.
