3. Let D = {2, 5}, E = {1,4, 7,8}, and F = {2,6, 10}. Determine whether the following statement is true or false. Justify your answer. Vx € D, 3y E E such that Vz E F, (x is odd + y + z is even) 4. Taking the long view on your education, you go to Prestige Corporation and ask what you should do in college to be hired when you graduate. The personnel director replies that you will be hired only if you major in mathematics or computer science, get a B average or better, and take accounting. You do, in fact, become a math major, get a B+ average, and take accounting. You return to Prestige Corporation, make a formal application, and are turned down. Did the personnel director lie to you? Explain.

How to slove the number 3 and number 4 questions 

18:41 4 5.8KB/s Ol O75 % 1. The computer scientists Richard Conway and David Gries once wrote: The absence of error messages during translation of a computer program is only a necessary and not a sufficient condition for reasonable (program) correctness. Rewrite this statement without using the words necessary or sufficient. (You are allowed to rewrite it into two sentences if it works better.) 2. Let p denote "3x E Z such that P(x)" and q denote "3x E R such that P(x)". Give a simple definition for the predicate P(x) (but do not use “x ¢ Z") so that q is true but p is false. Justify your answer. 3. Let D = {2, 5}, E = {1,4,7,8}, and F = statement is true or false. Justify your answer. {2,6, 10}.

The premise that should come first has been identified for you. Reorder the other four premises and at the same time, rewrite the statements in if-then form and replace some of them by their contrapositive if necessary. (Premises) (i) The arguments in these examples are not arranged in regular order like the ones I am used to. • I never grumble at an example unless it gives me a headache. • No easy examples make my head ache. • When I work a logic example without grumbling, you may be sure it is one I under- stand. • I can't understand examples if the arguments are not arranged in regular order like the ones I am used to. (Conclusion) These examples are not easy.
