We must show that no two of these sum to a number on this list. Therefore the statement will be true as long as we choose the domain to be anything with size 2such as the United States presidents named Bush. Since Carlos and Diana are making contradictory statements, the liar must be one of them we could have used this approach in part a as well.

Supplementary Exercises 31 Therefore the two propositions are logically equivalent. I’d like to read this book on Kindle Don’t have a Kindle? The truth table is as follows.

Then p is false. By Exercise 26, the product is rational.

Discrete Mathematics and Its Applications (6th edition) – Solutions (1) | Quang Mai –

Without loss of generality, we number the squares from 1 to 25, starting in the top row and proceeding left to right in each row; and we assume that squares 5 upper right corner21 lower left cornerand 25 lower right corner are the missing ones. This is an example of a trivial proof, since we merely showed that the conclusion was true. See all reviews. This was probably one of the worst-written textbooks I’ve used. On the other hand, if P x is false for all xthen both sides are false.


Finally, the second premise implies that if Tweety is a large bird, then Tweety does not live on honey. Note that this is vacuously true for domains with one element.

Logic and Proofs c First we rewrite this using Table 7 in Section 1. By Exercise 39, at least one of the sums must be greater than or equal to Solktions H must be false. Color the squares in order using the colors red, blue, green, yellow in that order repeatedly, starting in the upper left corner and proceeding row by row, from left to right in each row.

Maathematics our hypothesis, one of two things must be true.

The only case in which this is false is when s is false and both e and d are true. If Jones and Williams are the innocent truth-tellers, then we again get a contradiction, since Jones says that he did not know Cooper and was out of town, but Williams says he saw Jones with Cooper presumably in town, and presumably if we was with him, then he knew him.

Alexa Actionable Analytics for the Web. To construct the truth table for a compound proposition, we work from the inside out. It’s not only useless, it only served to confuse me and was a waste of my time.

Therefore without loss of generality, we can assume that we usewhich then forces,, andand we are stuck once again. We want to conclude r. Amazon Drive Cloud storage from Amazon. Then we drew at most one of each color.

Note that part b and part c are not the sorts of things one would normally say. Loose Leaf Verified Purchase. Instructors Choose a Different One. But these two pairs are not equivalent to each other.

Therefore, if we remove one black square and one white square, this closed path decomposes into two paths, each of which starts in one color and ends in the other color and therefore has even length. By Exercise 6, this tells us that mn is odd, and our proof is complete.
